Start tracking annotations that come from the classpath.

Due to a bug in metalava, we used to not track annotations that
come from the classpath. This CL updates to the latest metalava
and starts tracking these annotations.

This also fixes reified missing parent information fixed in UAST.

Test: ./gradlew updateApi
