**This API is not intended to ship. This is a temporary unstable hook for internal performance profiling.** This PR exposes `unstable_useContextWithBailout`, which takes a compare function in addition to Context. The comparison function is run to determine if Context propagation and render should bail out earlier. `unstable_useContextWithBailout` returns the full Context value, same as `useContext`. We can profile this API against `useContext` to better measure the cost of Context value updates and gather more data around propagation and render performance. The bailout logic and test cases are based on https://github.com/facebook/react/pull/20646 Additionally, this implementation allows multiple values to be compared in one hook by returning a tuple to avoid requiring additional Context consumer hooks.
