Summary:
This diff adds the `performance.reactNativeStartupTiming` API to the performance global object for RN. This property does not exist in web, and we are free to make up our own list of properties in the startup metrics to track RN app startup process. In our case, we have the following six properties to begin with (we may extend and add more to this list in the future):
```
- `(start|end)Time`: The time ‘zero’ for the startup timing and the end of app startup. RN has no knowledge of app start time, which will be provided by the platform. The `endTime` will be the time when the first JS bundle finishes executing (Note that RN supports multiple JS bundles, which can be loaded async)
- `executeJavaScriptBundleEntryPoint(Start|End)`: The time for RN to execute the JS entry point (and finish all sync job)
```
Changelog:
[General][Added] - Add new JS performance API to support getting RN app startup timings

Pull Request resolved: https://github.com/facebook/react-native/pull/36312
## Changelog:
[Internal] -
`clearMarks` and `clearMeasures` methods are incidental to the `NativePerformance` TurboModule functionality, as in reality this responsibility belongs more on the `NativePerformanceObserver` and `PerformanceEntryReporter` side.
This is something that [the standard indirectly suggests](https://www.w3.org/TR/user-timing/#clearmarks-method) as well (referencing [performance entry buffer](https://www.w3.org/TR/performance-timeline/#dfn-performance-entry-buffer)).
The new implementation should be also a little bit more efficient, as it avoids calling the predicate for each entry.
Finally (and frankly, the main reason for this change, from my perspective), it will simplify mocking/testing the JS part of the PerfAPI code.

Summary:
This diff adds new performance API `memory`, which is a read-only property that gets the current JS heap size from native side.
Note that the JSI API returns an unordered map with unknown list of memory information, which is different from the [web spec](https://fburl.com/p0vpbt33). We may enforce specific memory info type on the JSI API so that it can be properly translate to the web spec.
- Update the JS spec
- Update Native implementation and return memory information with JSI API `jsi::instrumentation()::getHeapInfo()`
- Add native performance module to catalyst package
Changelog:
[General][Added] - Add performance memory API with native memory Info

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:
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.

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.
