[DevTools] Remove Timeline profiler tab, suggest React Performance tracks (#37186)

Cleaning up the Timeline profiler in the next commit on top of this one.

If user is debugging React 19.2+, we will show a suggestion to record a
trace on Performance panel. Otherwise, we will suggest to upgrade to
React 19.2 to unlock Performance tracks.
