Summary:

Changelog: [Internal]

React started using clearMeasures in react/react#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.
