[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.
