EW-9466 EW-9596 Add perf event marking to performance.now()

This commit contains two changes:

- Adds an IsolateLimitEnforcer::markPerfEvent(name) function whose
  default implementation is a no-op. Its internal implementation injects
  perf counter data into our perf_event observability system.
- Calls the function from performance.now(). This allows us to see what
  our perf_event counters are at the moment in time when JS calls that
  API.
