Implement EventCounts Web Performance API for React Native (#36181)

Browse Source 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36181

[Changelog][Internal]

Implements EventCounts API (`Performance.eventCounts`) for Web Performance, according to the W3C standard, see the specs here: https://www.w3.org/TR/event-timing/#eventcounts

The rationale for why we need it is to support some advanced metrics computations, such as a ratio of "slow events" to total event count, per event type.
