Summary:
This diff splits up the current `createTimer` method (which is used for setTimeout, setInterval, etc.) into two methods, `createTimer` and `createAndMaybeCallTimer`. The latter is what's used by the existing Timing native module, and it preserves the existing behavior of this function.
What's the difference? The current implementation of createTimer makes some assumptions about how it's called - namely, that it's called from JS asynchronously (using the bridge). Right now when you create a timer from JS, the JSTimers module passes in the timestamp for when the timer was created; in the native `createTimer`, we compare this timestamp to the current time, and if we find the timer has already expired, we immediately invoke the callback.
Presumably this is done because we don't know how much time has elapsed since when the timer was scheduled in JS, and we want to make sure that it's called as soon as possible. Of course, this also means that `setTimeout(0)` will be immediately invoked, too, without waiting for the next frame.
This all sounds fine, until we take a look at immediates. Immediates are currently implemented entirely in JS, and are called by the JS bridge; before returning control to native, we flush the immediates queue.
This means that the current behavior is: 1) `setImmediate()` is always invoked before `setTimeout(0)`; 2) `setTimeout(0)` is invoked as soon as possible, before the next frame.
However, this changes with bridgeless RN. With bridgeless RN, the native module methods are being replaced by C++ host functions, which are called synchronously. So if we keep the current logic in JavaTimerManager (where it checks if the timer has already expired), then `setTimeout(0)` will be invoked **before** immediates are called.
So the change that I'm making for bridgeless RN is to always wait until the next frame before calling timers. This preserves the order of immediates/timers, although it does mean that `setTimeout(0)` will no longer be called as soon as possible. Of the two options, this seems preferable.

Summary:
The next step to making our existing timers logic usable outside of the context of the native module. This diff removes the bridge access through ReactContext in JavaTimerManager, and instead relies on a delegate that implements the JSTimers interface. I'm reusing the JSTimers interface for convenience even though it extends JavaScriptModule, which I don't plan on using for bridgeless RN.
Also changing from ReadableArray to ReadableNativeArray so that it can be directly accessed from C++.

The commit had to be reverted because it caused a crash when using remote debugging in chrome. This is normal since jsi is not available in that environment. The crash was caused by `jsContext.get()` being 0, then being dereferenced later in c++. We can simply skip initializing the blob collector in this case.

Summary:
I wanted to configure the RN dev menu without having to write native code. This is pretty useful in a greenfield app since it avoids having to write a custom native module for both platforms (and might enable the feature for expo too).
This ended up a bit more involved than planned since callbacks can only be called once. I needed to convert the `DevSettings` module to a `NativeEventEmitter` and use events when buttons are clicked. This means creating a JS wrapper for it. Currently it does not export all methods, they can be added in follow ups as needed.

Summary:
@public
`reportException` is a new method on `NativeExceptionsManager` that is designed to allow more structured and flexible JS error reporting. `reportFatalException` and `reportSoftException` are now deprecated.
In addition to all the usual exception fields, `reportException` also accepts an `extraData` property which the JS exception handler can populate with arbitrary JSON-serialisable data (here: the raw stack trace, the current JS engine, and the number of frames popped off the call stack by the exception handler). The contents of `extraData` get attached as JSON to the `JavascriptException` instance (or just logged, in the case of `console.error`).
This change is backwards compatible in two senses:
1. We have a JS fallback that uses `reportFatalException` and `reportSoftException` if the new native method is unavailable.
2. We have a Java fallback that implements `reportFatalException` and `reportSoftException` in terms of `reportException`.
Naturally, both fallbacks mentioned above discard `extraData`.
NOTE: The current implementation is Android-only; for the time being, iOS will continue to use the JS fallback.
While we're in `ExceptionsManager.js`, this also changes `dismissRedbox()` to be optional (which it is, since it's Android-only); existing call sites already guard it with a null check so this requires no other changes.

D15826082 was reverted because it introduced a crash in Ads Manager for Android (see P67222724).
This diff fixes the crash and re-applies D15826082. The problem was that `jni::findClassStatic` in the destructor of BlobCollector.cpp couldn't find the Java class `com/facebook/react/modules/blob/BlobModule` and crashed the app.
JNI didn't seem to have access to the Java class loader probably because the destructor was called from a non-Java thread (https://our.intern.facebook.com/intern/wiki/Fbjni/environment-and-thread-management/?vitals_event=wiki_click_navigation_link#threads). The fix is to wrap the code in the destructor inside `ThreadScope::WithClassLoader `, which will allow to run code that has full access to Java as though you were running in a Java thread.

D15279651 introduced a crash for Oculus Twilight on Android (T45199437), so it was reverted by D15611385.
This diff fixes the crash and re-applies D15279651. The problem was that ProGuard renamed BlobModule.remove() to BlobModule.release(), but the C++ code in `BlobCollector.cpp` still expected the old name. I confirmed this by looking at the Extracted Symbols file for the build which introduces the crash (https://fburl.com/mobile/ud40od3i):
```
com.facebook.react.modules.blob.BlobModule -> com.facebook.react.modules.blob.BlobModule:
...
8190:8193:void remove(java.lang.String):190:193 -> release
...
```
See the full log file here: https://fburl.com/pn02bwkb.
The solution is to annotate the method with `DoNotStrip` so that ProGuard doesn't rename it.

Summary:
`setTimeout` inside a headless JS task does not always works; the function does not get invoked until the user starts an `Activity`.
This was attempted to be used in the context of widgets. When the widget update or user interaction causes the process and React context to be created, the headless JS task may run before other app-specific JS initialisation logic has completed. If it's not possible to change the behaviour of the pre-requisites to be synchronous, then the headless JS task blocks such asynchronous JS work that it may depend on. A primitive solution is the use of `setTimeout` in order to wait for the pre-conditions to be met before continuing with the rest of the headless JS task. But as the function passed to `setTimeout` is not always called, the task will not run to completion.
This PR solves this scenario by allowing the task to be retried again with a delay. If the task returns a promise that resolves to a `{'timeout': number}` object, `AppRegistry.js` will not notify that the task has finished as per master, instead it will tell `HeadlessJsContext` to `startTask` again (cleaning up any posted `Runnable`s beforehand) via a `Handler` within the `HeadlessJsContext`.
Documentation also updated here: https://github.com/facebook/react-native-website/pull/771
### AppRegistry.js
If the task provider does not return any data, or if the data it returns does not contain `timeout` as a number, then it behaves as `master`; notifies that the task has finished. If the response does contain `{timeout: number}`, then it will attempt to queue a retry. If that fails, then it will behaves as if the task provider returned no response i.e. behaves as `master` again. If the retry was successfully queued, then there is nothing to do as we do not want the `Service` to stop itself.
### HeadlessJsTaskSupportModule.java
Similar to notify start/finished, we simply check if the context is running, and if so, pass the request onto `HeadlessJsTaskContext`. The only difference here is that we return a `Promise`, so that `AppRegistry`, as above, knows whether the enqueuing failed and thus needs to perform the usual task clean-up.
### HeadlessJsTaskContext.java
Before retrying, we need to clean-up any timeout `Runnable`'s posted for the first attempt. Then we need to copy the task config so that if this retry (second attempt) also fails, then on the third attempt (second retry) we do not run into a consumed exception. This is also why in `startTask` we copy the config before putting it in the `Map`, so that the initial attempt does leave the config's in the map as consumed. Then we post a `Runnable` to call `startTask` on the main thread's `Handler`. We use the same `taskId` because the `Service` is keeping track of active task IDs in order to calculate whether it needs to `stopSelf`. This negates the need to inform the `Service` of a new task id and us having to remove the old one.

### Problem
According to https://github.com/facebook/react-native/issues/9145, the `--port` setting is not respected when executing `react-native run-android`. The templates that report things like what port the dev server runs on are hard coded as well.
### Solution
This commit replaces the hardcoded instances of port 8081 on Android with a build configuration property. This allows setting of the port React Native Android connects to for the local build server.
For this change to work, there must also be an update to the react native CLI to pass along this setting:
https://github.com/react-native-community/react-native-cli/compare/master...nhunzaker:9145-android-no-port-hardcode-cli
To avoid some noise on their end, I figured I wouldn't submit a PR until it's this approach is deemed workable.

Summary:
React Native has a `NativeModule` to manipulate programmatically the dev menu options (live reload, hot reload, remote debugging, etc), called [`DevSettings`](https://github.com/facebook/react-native/blob/master/React/Modules/RCTDevSettings.mm#L120). However this module is only available for iOS.
This PR brings the same `DevSettings` for Android, making it a cross-platform NativeModule.
Motivation: Right now if your app needs to programmatically reload RN, one option is to install [`react-native-restart`](https://www.npmjs.com/package/react-native-restart). It's a tiny dependency, but it's annoying to have to install it, while the code to do so is inside RN codebase. According to NPM, react-native-restart has ~12k weekly downloads, shows it's a recurring feature for many apps (my case).
Thus making `NativeModules.DevSettings` is a small increment in the codebase, just exposing the dev menu methods, to improve the Development Experience
[Android] [Added] - Add DevSetting native module (making it cross-platform)
With expection of `setIsShakeToShowDevMenuEnabled`, the following methods will be available for both platforms:
* reload
* setHotLoadingEnabled
* setIsDebuggingRemotely
* setIsShakeToShowDevMenuEnabled
* setLiveReloadEnabled
* setProfilingEnabled
* toggleElementInspector

Summary: This is removing packages and libraries from the repo. Any modified buck files simply change the redirect targets to something more appropriate (no logic actually changed)

Summary:
For a small subset of Android devices, the following line of code caused the device to crash
```
output.transferFrom(input, 0, Long.MAX_VALUE);
```
According to the [Java docs](https://docs.oracle.com/javase/1.5.0/docs/api/java/nio/channels/FileChannel.html), this is what the function does.
> Transfers bytes into this channel's file from the given readable byte channel.
An attempt is made to read up to count bytes from the source channel and write them to this channel's file starting at the given position. An invocation of this method may or may not transfer all of the requested bytes; whether or not it does so depends upon the natures and states of the channels. Fewer than the requested number of bytes will be transferred if the source channel has fewer than count bytes remaining, or if the source channel is non-blocking and has fewer than count bytes immediately available in its input buffer.
Hence, using `Long.MAX_VALUE` seemed to be the standard way to transfer all bytes from one channel to the other.
However, it appeared that for some reason on a subset of old Android devices, the device tries to allocate `count` bytes of memory before transferring the bytes. Obviously, this caused a crash because no device has that much memory. This was fixed transferring bytes using a 1MB buffer.
