Do not keep runtime invisible annotations in proguard.proguard

This updates the corresponding Android.bp file to keep the runtime invisible annotations, meaning this should be a no-op.

When RELEASE_R8_ONLY_RUNTIME_VISIBLE_ANNOTATIONS is enabled, keep_runtime_invisible_annotations will become a no-op, which should lead to all runtime invisible annotations being stripped from this build.
