Implement performance.timeOrigin (#53660)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53660

Changelog: [internal]

(This is internal because these APIs aren't enabled in OSS yet)

Implements `performance.timeOrigin` to allow converting timestamps from `performance.now()` to be based on the Unix epoch.

This implementation isn't fully spec-compliant to align with the current implementation of `performance.now()`, where the base of the clock is system boot time instead of app startup / navigation time.
