Follow up to #34093.
There's an issue where the skipFrames argument isn't part of the cache
key so the other parsers that expect skipping one frame might skip zero
and show the internal `fakeJSXDEV` callsite. Ideally we should include
the skipFrames as part of the cache key but we can also always just skip
one.
We'll need complete parsing of stack traces for both owner stacks and
async debug info so we need to expand the stack parsing capabilities a
bit. This refactors the source location extraction to use some helpers
we can use for other things too.
This is a fork of `ReactFlightStackConfigV8` which also supports
DevTools requirements like checking both `react_stack_bottom_frame` and
`react-stack-bottom-frame` as well as supporting Firefox stacks.
It also supports extracting the first frame of a component stack or the
last frame of an owner stack for the source location.
In RSC and other stacks now we use a lot of `ReactFunctionLocation` type
to represent the location of a function. I.e. the location of the
beginning of the function (the enclosing line/col) that is represented
by the "Source" of the function. This is also what the parent Component
Stacks represents.
As opposed to `ReactCallSite` which is what normal stack traces and
owner stacks represent. I.e. the line/column number of the callsite into
the next function.
We can start sharing more code by using the `ReactFunctionLocation` type
to represent the component source location and it also helps clarify
which ones are function locations and which ones are callsites as we
start adding more stack traces (e.g. for async debug info and owner
stack traces).
`react-stack-bottom-frame` -> `react_stack_bottom_frame`.
This survives `@babel/plugin-transform-function-name`, but now frames
will be displayed as `at Object.react_stack_bottom_frame (...)` in V8.
Checks that were relying on exact function name match were updated to
use either `.indexOf()` or `.includes()`
For backwards compatibility, both React DevTools and Flight Client will
look for both options. I am not so sure about the latter and if React
version is locked.
When we get the source location for "View source for this element" we
should be using the enclosing function of the callsite of the child. So
that we don't just point to some random line within the component.
This is similar to the technique in #33136.
This technique is now really better than the fake throw technique, when
available. So I now favor the owner technique. The only problem it's
only available in DEV and only if it has a child that's owned (and not
filtered).
We could implement this same technique for the error that's thrown in
the fake throwing solution. However, we really shouldn't need that at
all because for client components we should be able to call
`inspect(fn)` at least in Chrome which is even better.

done:
1. Fork [the repository](https://github.com/facebook/react) and create
your branch from `main`.
2. Run `yarn` in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch
TestName` is helpful in development.
5. Run `yarn test --prod` to test in the production environment. It
supports the same options as `yarn test`.
6. If you need a debugger, run `yarn test --debug --watch TestName`,
open `chrome://inspect`, and press "Inspect".
7. Format your code with
[prettier](https://github.com/prettier/prettier) (`yarn prettier`).
8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only
check changed files.

## Summary
<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->
When using React Devtools, calling `console.log('%s', null)` in userland
can cause it to throw an error:
```
TypeError: Cannot read properties of null (reading 'toString')
```
## How did you test this change?
Added a unit test.
<!--

## Summary
We have been getting unhandled `TypeError: Cannot convert object to
primitive value` errors in development that only occur when using
devtools. I tracked it down to `console.error()` calls coming from
Apollo Client where one of the arguments is an object without a
prototype (created with `Object.create(null)`). This causes
`formatConsoleArgumentsToSingleString()` in React's devtools to error as
the function does not defend against `String()` throwing an error.
My attempted fix is to introduce a `safeToString` function (naming
suggestions appreciated) which expects `String()` to throw on certain
object and in that case falls back to returning `[object Object]`, which
is what `String({})` would return.
## How did you test this change?
Added a new unit test.
Stacked on https://github.com/facebook/react/pull/30596. See [this
commit](4ba5e784bb).
Moving `formatWithStyles` and `formatConsoleArguments` to its own
modules, so that we can finally have a single implementation for these
and stop inlining them in RDT global hook object.
