Profiler integration with interaction-tracking package (#13253)
* Updated suspense fixture to use new interaction-tracking API

* Integrated Profiler API with interaction-tracking API (and added tests)

* Pass interaction Set (rather than Array) to Profiler onRender callback

* Removed some :any casts for enableInteractionTracking fields in FiberRoot type

* Refactored threadID calculation into a helper method

* Errors thrown by interaction tracking hooks use unhandledError to rethrow more safely.
Reverted try/finally change to ReactTestRendererScheduling

* Added a $FlowFixMe above the FiberRoot :any cast

* Reduce overhead from calling work-started hook

* Remove interaction-tracking wrap() references from unwind work in favor of managing suspense/interaction continuations in the scheduler
* Moved the logic for calling work-started hook from performWorkOnRoot() to renderRoot()

* Add interaction-tracking to bundle externals. Set feature flag to __PROFILE__

* Renamed the freezeInteractionCount flag and replaced one use-case with a method param

* let -> const

* Updated suspense fixture to handle recent API changes
