Enable PermissionAnnotationDetector for services.accessibility

Enable the linter and capture the current status by annotating Stub
classes with @SuppressWarnings.

The intent of this series of change is to ensure that all exposed Binder
methods from system_server are annotated. Service owners can start using
the following annotations on each method:
- @EnforcePermission, if a permission is required. The same annotation
  will be defined on the AIDL interface definition.
- @RequiresNoPermission, if no permission is required.
- @PermissionManuallyEnforced, if a specific mechanism to enforce
  permission is required.

See go/aidl-enforce-howto for more background information and details on
how to migrate interfaces.
