Summary:
Extends the WebPerformance API with ability to report events, [according to the standard](https://www.w3.org/TR/event-timing/#sec-performance-event-timing).
This is an API-only change, the actual reporting comes in a separate diff, to simplify reviewing.

Summary:
Prevents scenarios when internal performance buffer may grow indefinitely (e.g. due to a broken logging), communicating back to `PerformanceObserver` the corresponding amount of dropped entries, `droppedEntriesCount`, [according to the standard](https://w3c.github.io/performance-timeline/#dom-performanceobservercallbackoptions-droppedentriescount).
NOTE: The backwards compatibility check is failing, which is an orthogonal issue. I am looking into it and won't land this one before it is sorted.

Summary:
Now that D42097191 allows it, get rid of unused API in the related WebPerformance native modules (these were kept there only to pacify the backwards compatibility checks).

Changelog: [Internal]
This implements the C++ side logic of handling `Performance.measure` calls.
Since measures may refer to earlier logged marks by name, we need to keep track of the former. I also use a fixed size (circular) buffer to prevent the marks from piling forever.
Also adds implementation of clearing marks/measures, as per standard.

Summary:
[Changelog][Internal]
The NativePerformance module functionality corresponds to the [timing extensions of the Performance API standard interface](https://www.w3.org/TR/user-timing/#extensions-performance-interface).
As this is logically separate from `PerformanceObserver` (which may exist without it), it makes sense to have it as a different native module, so there is no coupling between both.

Pull Request resolved: https://github.com/facebook/react-native/pull/35526
[Changelog][Internal]
This closes the full loop according to the [technical design](https://fb.quip.com/MdqgAk1Eb2dV) of the WebPerf API implementation, with the main components and the working central data flow in place.
The next step is to add some buffering/throttling, as in this diff we just spawn an idle-priority task after every performance entry coming (even though they still naturally do come in batches, because they manage to accumulate before the task is executed).

Summary:
[Changelog][Internal]
Adds API definition for [Performance.mark](https://www.w3.org/TR/user-timing/#mark-method) support.
This is a bare bone implementation, that just logs events on the native side. The next step is the native logic for queuing, flushing etc.
Note that here I route both JS and native marks to native for now, for simplicity sake - ultimately this may not be what we want, as it may be more efficient to process marks, logged from JS, on the JS side.
