[Changelog][Internal]
Based on the internal discussion, we don't want to report `first-input` event types for RN (just use plain `event` instead), in the way that [Event Timing API standard suggests](https://www.w3.org/TR/event-timing), as this is doesn't have that clear semantics in the context of RN, also to keep it simpler.

Changelog: [Internal]
This adds definition of `PerformanceEventTiming` interface, according to the W3C standard, so that [event timing](https://www.w3.org/TR/event-timing) data can be reported from native (the C++ part is in the next diff).

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).

Summary:
Our implementation of `PerformanceObserver.prototype.observe` diverges a little bit from the [spec](https://w3c.github.io/performance-timeline/#dom-performanceobserver-observe) regarding the behavior when calling it multiple times. E.g.:
1. We don't throw errors if both `type ` and `entryTypes` are passed.
2. We don't throw errors if neither `type ` nor `entryTypes` are passed.
3. We don't throw errors if we call observe with `type` and we call again later with `entryTypes`, and vice versa.
4. The logic to consolidate entry types in subsequent observe calls is incorrect.
This fixes those issues and also applies some minor naming improvements.

Summary:
Changelog: [Internal]
This adds JS side implementation (including the API) for the `Performance.measure` functionality, [as described in the corresponding standard](https://www.w3.org/TR/user-timing/#measure-method).
The JS part is separated from the C++ implementation (further down the stack) to help the review being more focused.

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.
