Moti Zilberman 6764385c80 Type StackFrame fields as nullable
Summary: `parseErrorStack` (which uses the `stacktrace-parser` package) can return null file names, line numbers and column numbers. This diff updates the associated types and adds explicit null checks in some call sites.

Moti Zilberman 2dadb9e2b0 Move React error message formatting into ExceptionsManager
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.

Moti Zilberman 77125a1ac3 Use Metro support for auto-collapsing internal stack frames (#25839)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/25839

Changes `ExceptionsManager` to respect the `collapse` field in each symbolicated stack frame returned from Metro. This is ultimately driven by a Metro config option (which will have a default set in https://github.com/react-native-community/cli/pull/596).

This is part of a redesign of work done originally in https://github.com/facebook/react-native/pull/24662.

Moti Zilberman 3a825c0360 Introduce NativeExceptionsManager.reportException API
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.
