Summary:
## Overview
This diff is an RFC to port a logging feature from iOS to Android.
Changelog: [Internal]
## Motivation
On iOS we have the following log functions and behaviors available for logging native warnings and errors:
- **Warnings** (`RCTLogWarn`)
- Log level 'warn' to console
- Display warning in LogBox
- **Errors** (`RCTLogError`)
- Log level 'error' to console
- Display a native RedBox (needs converted to show a LogBox if available)
- **Logs**
- We also have `RCTLog`, `RCTTrace`, `RCTAdvice`, `RCTInfo`, which just log to the console.
In Java, we have:
- **Warnings**
- **None**, added in this diff
- **Errors** (`DevSupportManager.showNewJavaError`)
- Log level 'error' to console with `FLog.e`
- Display a native RedBox (needs converted to show a LogBox if available
- **Logs**
- `ReactSoftException` (crashes the app??)
- `ReactNoCrashSoftException` (only logs??)
- Others?
## Details
This diff adds a method to pair with `RCTLogWarn`, `DevSupportManager.showNewJavaWarning`, which will log to the console and show a LogBox warning if LogBox is available.
## Concerns
I have a few concerns/questions about the state of logging on Android:
- Should/can we move all of the logging to it's own class, like how RCTLog works?
- Why does some logging happen on DevSupportManager and some in other classes?
- If we moved it all to it's own class, how could we access the reactContext to call the RCTLog JS module

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:
This diff formats the Java class files inside xplat/js/react-native-github. Since google-java-format was enabled in D16071401 we want to codemode the existing code so that users don't have to deal with formatter lint noise at diff-time.
