Summary: public Kill `RCTPerfStats` and introduce the new `RCTPerfMonitor`, including memory usage, JSC heap size, number of RN views in screen, FPS (both on UI and JS threads) and more to come. It removes all the previous traces that were previous spread across the bridge and the dev menu and moves everything to be more contained, so the whole thing can be safely striped in production.
