Summary:
This diff adds handling for syntax errors.
## Strategy
To do this we introduce a new log level type syntax, giving us these levels with semantics:
- `warn` - console warns, show collapsed, dismissible
- `error` - console errors, show collapsed, dismissible
- `fatal` - thrown exceptions, show expanded, not dismissible
- `syntax` - thrown exceptions for invalid syntax, show expanded, not dismissible
Syntax errors shows expanded, covers all other errors, and are only dismissible when the syntax error is fixed and updated with Fast Refresh. Once the syntax error is fixed, it reveals any previously covered fatals, errors, or warnings behind it
In many ways, this makes syntax errors the highest level error.
## Visuals
Syntax errors also have their own display formatting. Stack traces for syntax errors don't make sense, so we don't show them. Instead, we show the syntax error message and a code frame for the error.
The code frame is also updated so that is doesn't wrap and is horizontally scrollable, making it easier to read.
## Detecting syntax errors
To detect syntax errors we've updated `LogBoxData.addException` to call the parse function `parseLogBoxException`. This method will perform a regex on the error message to detect:
- file name
- location
- error message
- codeframe
If this regex fails for any reason to find all four parts, we'll fall back to a fatal. Over time we'll update this regex to be more robust and handle more cases we've missed.

Summary:
Removes support for the non-standard `framesToPop` error property from React Native. Redboxes will now ignore this field. The way to skip uninformative frames in stack traces going forward is to use Metro's `customizeFrame` config option, for which the React Native CLI ships useful defaults (see: https://github.com/react-native-community/cli/pull/596, https://github.com/react-native-community/cli/pull/780)

Summary:
# Context
In https://github.com/facebook/react/pull/16141 we imported `ReactFiberErrorDialog` unchanged from React. That implementation was not idempotent: if passed the same error instance multiple times, it would amend its `message` property every time, eventually leading to bloat and low-signal logs.
The message bloat problem is most evident when rendering multiple `lazy()` components that expose the same Error reference to React (e.g. due to some cache that vends the same rejected Promise multiple times).
More broadly, there's a need for structured, machine-readable logging to replace stringly-typed interfaces in both the production and development use cases.
# This diff
* We leave the user-supplied `message` field intact and instead do all the formatting inside `ExceptionsManager`. To avoid needless complexity, this **doesn't** always have the exact same output as the old code (but it does come close). See tests for the specifics.
* The only mutation we do on React-captured error instances is setting the `componentStack` expando property. This replaces any previously-captured component stack rather than adding to it, and so doesn't create bloat.
* We also report the exception fields `componentStack`, unformatted `message` (as `originalMessage`) and `name` directly to `NativeExceptionsManager` for future use.

Summary: These warnings are both noisy and unactionable to product developers when you disconnect a Metro server. You also see them *after* the redbox is closed anyway, so you kind of already know if symbolication didn't work. So I'm downgrading it to a simple log.

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.

Summary:
Metro symbolication can be expensive in large apps. However, there is no need to symbolicate _runtime stacks from compile errors_. Those are pretty much useless anyway.
This will reduce the workload on Metro workers, and the delays when iterating with Fast Refresh, as the server will be busy much less often.
So I'm special-casing them and not sending the symbolication request anymore.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

Summary:
On iOS, `RCTRedBox` will not update the displayed stack trace if the message string sent with the update differs from the original error message. As JS errors are shown in two stages - before and after symbolication - there was previously a case where the message would differ between the two `updateExceptionMessage` calls, blocking the update and leaving only the unsymbolicated trace visible. This diff fixes that.
Longer term, we should also change `RCTRedBox`'s logic to rely on the JS-provided `exceptionID` instead of the message string - similar to what we do on Android.
