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 c5180f4bfb Test more of ExceptionsManager
Summary: Renames `ReactFiberErrorDialog-test` to `ExceptionsManager-test` and adds tests for `console.error` and exceptions not captured by React. Some of this functionality is covered by the RNTester integration tests, but this JS test suite is both more comprehensive and easier to iterate against.
