Create ErrorProne lint rule for RoSystemFeatures usage

Create a basic ErrorProne rule that can be used for linting and
in-place updates of calls to system feature queries. A similar
Android Lint rule will be used after work that would enable in-place
updates for both Java/Kotlin sources, but for now an ErrorProne rule
handles most of the impactful callsites.

A follow-up change will add this lint rule to system_server targets
after performing a batch migration update.
