Previously, turbine ran annotation processors, javac ran them, and
errorprone also ran them.

This CL reuses the files that were generated when turbine ran annotation
processors so that javac and errorprone no longer ran annotation
processors.

Saves 4.6s on Base Java Signature Change (153.6s -> 149.0s).
More importantly unlocks javac sharding (since javac now depends on
turbine).
