Mark wrapper descriptors as method descriptors (#9286)

* Mark wrapper descriptors as method descriptors

Match CPython 3.15 wrapper_descriptor flags so existing method lookup
can use the descriptor's direct receiver-prepending dispatch path.

Assisted-by: OpenAI Codex:model-version-unavailable

* Retire fixed wrapper monitoring expected failure

Regenerate test_monitoring from pinned CPython 3.15.0 with the updater, preserving every other adaptation. The METHOD_DESCRIPTOR flag now supplies the canonical receiver in int.__repr__ CALL/C_RETURN events.
