Request: add inspection of suggesting to add annotations of WorkerThread/UiThread/AnyThread based on usage

[AndroidDeveloperLB]

If in all calls of a function "foo", we call it from the UI-thread, it could suggest us to add the UiThread annotation. Same for WorkerThread. If it's mixed, suggest to add "AnyThread" annotation.

You can also add a setting of how far to suggest, because if a function is private, it's safer to use the quick-fix than when it's public. That's especially important for the case of library-modules.

Sounds useful, I'd accept a contribution.

@Miha-x64 Hopefully someone could offer it. For now I've also requested this on the issue tracker: https://issuetracker.google.com/issues/244694784
