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

Summary:
Adding another method to ReactMarker to log a marker with both a tag and an instanceKey. The instanceKey is used to attach the event to the correct marker instance - this is used already in Java, but not in C++ yet.
The way that ReactMarker is currently set up makes this change a little more complex/confusing. For some reason I'm not totally clear on, we're using C-style exports with some platforms-specific ifdefs in ReactMarker.h (even though the impl is .cpp?). And we swap out the implementation for `logTaggedMarker` at runtime in platform-specific code (JReactMarker and RCTCxxBridge).
In this diff, I just add a new function alongside `logTaggedMarker`, `logTaggedMarkerWithInstanceKey`. I did it this way because I figured modifying `logTaggedMarker` to add an argument would be a breaking change.

Summary:
We are moving towards 100%-prettified files. That's the first step when we apply Clang Format for `ReactCommon`.
