Add support for recording Runtime Profiles for multiple JavaScript threads (#53535)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53535

# Changelog: [Internal]

This primarily addressed the case when we have captured a Runtime Profile during the app startup. The Hermes Runtime is created on the main thread, so the first few samples will be recorded there, but then it will be moved to JavaScript thread.
