Summary:
Certain turbomodules set `requiresMainQueueSetup` to true. This is b/c they use some fancy APIs in setup that need main queue.
TurboModuleManager mostly adhered to this restriction, the only case it didn't is when setting bridge. There is possibility that this happens on JS thread, which would crash the app for these certain TM. This diff fixes that.

Summary:
## The Problem
1. `CatalystInstanceImpl` indirectly holds on to the `jsi::Runtime`. When you destroy `CatalystInstanceImpl`, you destroy the `jsi::Runtime`. As a part of reloading React Native, we destroy and re-create `CatalystInstanceImpl`, which destroys and re-creates the `jsi::Runtime`.
2. When JS passes in a callback to a TurboModule method, we take that callback (a `jsi::Function`) and wrap it in a Java `Callback` (implemented by `JCxxCallbackImpl`). This Java `Callback`, when executed, schedules the `jsi::Function` to be invoked on a Java thread at a later point in time. **Note:** The Java NativeModule can hold on to the Java `Callback` (and, by transitivity, the `jsi::Function`) for potentially forever.
3. It is a requirement of `jsi::Runtime` that all objects associated with the Runtime (ex: `jsi::Function`) must be destroyed before the Runtime itself is destroyed. See: https://fburl.com/m3mqk6wt
### jsi.h
```
/// .................................................... In addition, to
/// make shutdown safe, destruction of objects associated with the Runtime
/// must be destroyed before the Runtime is destroyed, or from the
/// destructor of a managed HostObject or HostFunction. Informally, this
/// means that the main source of unsafe behavior is to hold a jsi object

/// is shut down. If your lifecycle is such that avoiding this is hard,
/// you will probably need to do use your own locks.
class Runtime {
public:
virtual ~Runtime();
```
Therefore, when you delete `CatalystInstanceImpl`, you could end up with a situation where the `jsi::Runtime` is destroyed before all `jsi::Function`s are destroyed. In dev, this leads the program to crash when you reload the app after having used a TurboModule method that uses callbacks.
## The Solution
If the only reference to a `HostObject` or a `HostFunction` is in the JS Heap, then the `HostObject` and `HostFunction` destructors can destroy JSI objects. The TurboModule cache is the only thing, aside from the JS Heap, that holds a reference to all C++ TurboModules. But that cache (and the entire native side of `TurboModuleManager`) is destroyed when we call `mHybridData.resetNative()` in `TurboModuleManager.onCatalystInstanceDestroy()` in D16552730. (I verified this by commenting out `mHybridData.resetNative()` and placing a breakpoint in the destructor of `JavaTurboModule`). So, when we're cleaning up `TurboModuleManager`, the only reference to a Java TurboModule is the JS Heap. Therefore, it's safe and correct for us to destroy all `jsi::Function`s created by the Java TurboModule in `~JavaTurboModule`. So, in this diff, I keep a set of all `CallbackWrappers`, and explicitly call `destroy()` on them in the `JavaTurboModule` destructor. Note that since `~JavaTurboModule` accesses `callbackWrappers_`, it must be executed on the JS Thread, since `createJavaCallbackFromJSIFunction` also accesses `callbackWrappers_` on the JS Thread.
For additional safety, I also eagerly destroyed the `jsi::Function` after it's been invoked once. I'm not yet sure if we only want JS callbacks to only ever be invoked once. So, I've created a Task to document this work: T48128233.

Summary:
When you call a TurboModule method with JS arguments, we necessarily convert these JS args to Java objects/primitives before passing them to the Java implementation of the method. The problem is that we let the type of the JS arg dictate the type of the Java object/primitive to convert said arg to. This means that if a JS developer passes in an `number` to a function that expects an `Array`, we'll convert the number to a `double` and try to call the Java method with that `double`, when it actually expects a `ReadableArray`. This will trigger a JNI error, and crash the program. Ideally, we should be able to catch these type mismatches early on.
In this diff, on every TurboModule method call, I parse the method signature to determine the Java type of each JS argument. Then, for any argument, if the JS arg and the Java arg types aren't compatible, I raise an exception, which gets displayed as a RedBox in development. This diff also implements support for `?number` and `?boolean` argument and return types in TurboModules.

This is the first step towards fixing https://github.com/facebook/react-native/issues/25349. These are the changes to the podspec to correctly update dependencies and build config that will cause any breaking change for users or libraries.
I am breaking these changes out from https://github.com/facebook/react-native/pull/25393 as suggested by fkgozali in https://github.com/facebook/react-native/pull/25393#issuecomment-508322884.
These are the changes:
- Made C++ headers in `React-Core` private by default so that ObjC files can import the module without failures.
- Reduced the number of `yoga` headers that are exposed for the same reason as above. As far as I can see this doesn't cause issues but we can find another solution if it does.
- Adding some missing dependencies to fix undefined symbols errors.
- Added `DoubleConversion` to `HEADER_SEARCH_PATHS` where it was missing.

There can be a race condition between bridge invalidation (hence TM binding invalidation) with pending Promise reject/resolve invocation. If invalidation happens first, invoking the resolve/reject from ObjC class might end up accessing destroyed PromiseWrapper, causing hard crash randomly.

Summary:
With the introduction of TurboModules, it would be beneficial to measure the setup time of these modules, as we currently have it in place for NativeModules.
The instantiation of the TMs occurs in the `RCTTurboModuleManager`. In order to successfully measure the time it took to setup the module, we need to ensure that we don't take into account cached modules. As such, we need to:
1. Check if module is in `_turboModuleCache`
a. Start mark for `RCTPLTurboModuleSetup` tag if not found
2. Get the TM via `[self provideTurboModule:]`
3. Check if module is in `_turboModuleCache`
a. Stop mark for `RCTPLTurboModuleSetup` if we did not find module in cache prior to **step 2** and if it's now present in the cache.
b. Notify about setup time if the above is true.
4. Return TM

Summary:
JSCallInvoker requires a `std::weak_ptr<Instance>` to create. In our C++, `CatalystInstance` is responsible for creating this `Instance` object. This `CatalystInstance` C++ initialization is separate from the `TurboModuleManager` C++ initialization. Therefore, in this diff, I made `CatalystInstance` responsible for creating the `JSCallInvoker`. It then exposes the `JSCallInvoker` using a hybrid class called `JSCallInvokerHolder`, which contains a `std::shared_ptr<JSCallInvoker>` member variable. Using `CatalystInstance.getJSCallInvokerHolder()` in TurboModuleManager.java, we get a handle to this hybrid container. Then, we pass it this hybrid object to `TurboModuleManager::initHybrid`, which retrieves the `std::shared_ptr<JSCallInvoker>` from the `JavaJSCallInvokerHandler`.
There were a few cyclic dependencies, so I had to break down the buck targets:
- `CatalystInstanceImpl.java` depends on `JSCallInvokerHolderImpl.java`, and `TurboModuleManager.java` depends on classes that are packaged with `CatalystInstanceImpl.java`. So, I had to put `JSCallInvokerHolderImpl.java` in its own buck target.
- `CatalystInstance.cpp` depends on `JavaJSCallInvokerHolder.cpp`, and `TurboModuleManager.cpp` depends on classes that are build with `CatalystInstance.cpp`. So, I had to put `JavaJSCallInvokerHolder.cpp` in its own buck target. To make things simpler, I also moved `JSCallInvoker.{cpp,h}` files into the same buck target as `JavaJSCallInvokerHolder.{cpp,h}`.
I think these steps should be enough to create the TurboModuleManager without needing a bridge:
1. Make `JSCallInvoker` an abstract base class.
2. On Android, create another derived class of `JSCallInvoker` that doesn't depend on Instance.
3. Create `JavaJSCallInvokerHolder` using an instance of this new class somewhere in C++.
4. Pass this instance of `JavaJSCallInvokerHolder` to Java and use it to create/instatiate `TurboModuleManager`.
Regarding steps 1 and 2, we can also make JSCallInvoker accept a lambda.

If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

* RCTSampleTurboModule (traditional objc module)
* RCTSampleTurboCxxModule (objc++ module using CxxModule)
* SampleTurboModule (pure C++ impl of a TurboModule, no ObjC)
As noted in some files, they need to be codegen'ed based on the `NativeSampleTurboModule.js` (Flow type). The codegen script is not yet usable in OSS (we'll work on it some time in H2 2019). For now, these files need to be manually synced with Flow type.

Summary:
For CocoaPods variant only: install TurboModule binding so that sample modules can start using it. This commit only installs `global.__turboModuleProxy` - no sample module is provided.
Note: RNTester.xcodeproj will NOT have TurboModule enabled, due to complication in the .xcodeproj setup (doable, but maybe for some other time...)
To test:
```
console.error(global.__turboModuleProxy == null ? 'BOO' : 'YAY!');
```
Saw `YAY!` in RNTester pod version.

Summary:
There is a timing issue when reloading the bridge (in dev mode) and the tear down of the TurboModules. This causes `Instance` to never get freed, hence the "bridge" isn't cleaning up properly. The side effect can be bogus error saying that it's unable to find a module.
To address this, JSCallInvoker should just take in weak_ptr<Instance>.

Summary:
If a NativeModule method requires an optional boolean argument, our codegen translates those optional booleans into `NSNumber*` instead of `BOOL`. The reason why is probably because this is the closest object analogue to `BOOL` in Objective C. The same boxing occurs with numbers. If the type of a number argument in JavaScript is optional, we'll map it to the `NSNumber*` Objective C type instead of `double`. Our existing TurboModules argument conversion code would not take this behaviour into account. Therefore, we'd try to insert a `BOOL` where the `NSInvocation` would expect a `NSNumber*`. This, in turn, would cause the app to crash. (Why would it crash at the point of NSInvocation retainArguments, I'm still not sure).
Our flow typechecking ensures that if the type of a method argument is a boolean, we pass in a boolean. Therefore, on the Native side, if we detect a boolean, we can check the type of the Native argument to see whether we should box the primitive. If the native argument type is an object, then we know it has to be an `NSNumber*` in both cases, so we simply wrap the `BOOL` or `double` in a `NSNumber*`.
