Automated rollback of commit 4b7f0e4.

*** Reason for rollback *** Roll forward, and disable the check in `tools/jdk/config/error_prone/build_defs.bzl` until the cleanup is done. *** Original change description *** Automated rollback of commit a3fdf64. *** Reason for rollback *** Requires a large number of fixes throughout the depot. I am not sure that that was intended, but if it was then those fixes should be made separately from the regularly-scheduled JavaBuilder release. A *subset* of the fixes, before I gave up, is here: unknown commit. *** Original change description *** Generalize InjectScopeOrQualifierAnnotationRetention to MissingRuntimeRetention *** *** PiperOrigin-RevId: 650310818
