rust_binder: Implement BINDER_DEBUG_USER_ERROR for refcounting and death notifications

Browse source

This adds dynamic debug logs for:
- Decrementing handle reference counts that are already zero.
- Mismatched reference states (calling inc_ref_done with no active
  inc_refs, or using a weak reference as a strong reference).
- Requesting or clearing death notifications on invalid references,
  already active notifications, or with mismatched cookies.
