Subject: [PATCH] fix: add clearMarks and clearMeasures to performance global
 stub

Summary:
# Changelog: [Internal]

React started using `clearMeasures` in https://github.com/facebook/react/pull/34803. It only does it if `performance.measure()` is defined. This should be enough for a  feature check of User Timings API presence, but out stub doesn't follow the same spec.

Adding `clearMarks()` and `clearMeasures()` stubs to the object.
