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.

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:
Makes sure that the global (standard) `performance` instance is initialized to still both provide `Performance.now()` as before, but also allows for the newly implemented functionality from the WebPerf API, such as marks/measures.

Summary:
Makes sure that we don't spam too often the JS performance entry reporting callback, which further dispatches entries to `PerformanceObserver` instances.
The logic is as following:
* ~~~If internal buffer of entries reaches the limit, we schedule the callback (with background priority)~~~
*~~~ Once the callback is processed, we schedule the next flush after a timeout of 500ms, this will also be scheduled from native with background priority~~~
* ~~~Whenever new performance type starts to be observed, we also schedule the callback, in order to prime the above~~~
* Schedule the flush with low priority, whenever there is the first entry coming into an empty buffer, and rely on the Scheduler to "do the right thing" when asked to flush it with background priority and not doo it exceedingly often (see the prolonged discussion)

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:
We're currently showing warnings when we call `performanceObserver.observe` and the native module for performance observers isn't available, but we don't do the same for `performance.mark`, `performance.measure`, etc.
This adds the warning in those cases.

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.

[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.
