services.core.unboosted - call PermissionEnforcer helper on methods annotated with @EnforcePermission

Migrates all existing java methods annotated with @EnforcePermission
such that they call the super.<methodName>_enforcePermission
method provided by PermissionEnforcer.

This required by the @EnforcePermission annotation, but is currently a
no-op, and will be switched on with ag/20325484.

This CL migrates incremental additions made since the original LSC
ag/20189550.
