High level breakdown of this commit:
* Add a enableSchedulingProfiling feature flag.
* Add functions that call User Timing APIs to a new SchedulingProfiler file. The file follows DebugTracing's structure.
* Add user timing marks to places where DebugTracing logs.
* Add user timing marks to most other places where @bvaughn's original draft DebugTracing branch marks.
* Tests added
* More context (and discussions with @bvaughn) available at our internal PR MLH-Fellowship#11 and issue MLH-Fellowship#5.
Similar to DebugTracing, we've only added scheduling profiling calls to the old reconciler fork.

* add unit test asserting internal hooks state is reset
* Reset internal hooks state before rendering
* reset hooks state on error
* Use expect...toThrow instead of try/catch in test
* reset dev-only hooks state inside resetHooksState
* reset currentlyRenderingComponent to null
* Rename internal variables
This disambiguates "optional"/"required" because that terminology is taken by optional chaining.
* Handle optional member chains
* Update comment

* Revert "Fix ExhaustiveDeps ESLint rule throwing with optional chaining (#19260)"
This reverts commit 0f84b0f02b.
* Re-add a test from #19260
* Remove all code for optional chaining support
* Consistently treat optional chaining as regular chaining
This is not ideal because our suggestions use normal chaining. But it gets rid of all current edge cases.
* Add more tests
* More consistency in treating normal and optional expressions
* Add regression tests for every occurrence of Optional*
* Initial currentLanePriority implementation
* Minor updates from review
* Fix typos and enable flag
* Fix feature flags and lint
* Fix simple event tests by switching to withSuspenseConfig
* Don't lower the priority of setPending in startTransition below InputContinuous
* Move currentUpdateLanePriority in commit root into the first effect block
* Refactor requestUpdateLane to log for priority mismatches
Also verifies that the update lane priority matches the scheduler lane priority before using it
* Fix four tests by adding ReactDOM.unstable_runWithPriority
* Fix partial hydration when using update lane priority
* Fix partial hydration when using update lane priority
* Rename feature flag and only log for now
* Move unstable_runWithPriority to ReactFiberReconciler
* Add unstable_runWithPriority to ReactNoopPersistent too
* Bug fixes and performance improvements
* Initial currentLanePriority implementation
* Minor updates from review

Certain code patterns using optional chaining syntax causes
eslint-plugin-react-hooks to throw an error.
We can avoid the throw by adding some guards. I didn't read through the
code to understand how it works, I just added a guard to every place
where it threw, so maybe there is a better fix closer to the root cause
than what I have here.
In my test case, I noticed that the optional chaining that was used in
the code was not included in the suggestions description or output,
but it seems like it should be. This might make a nice future
improvement on top of this fix, so I left a TODO comment to that effect.

* Re-enabled DebugTracing feature for old reconciler fork
It was temporarily removed by @sebmarkbage via PR #18697. Newly re-added tracing is simplified, since the lane(s) data type does not require the (lossy) conversion between priority and expiration time values.
@sebmarkbage mentioned that he removed this because it might get in the way of his planned discrete/sync refactor. I'm not sure if that concern still applies, but just in case- I have only re-added it to the old reconciler fork for now.
* Force Code Sandbox CI to re-run
