Michael Lippautz c58862c360 cppgc: Allow CrossThreadPersistent to access poisoned memory from GC ... Allow CrossThreadPersistent and its weak form to access ASAN poisoned memory from the GC entry points. In general, payloads of to-be-finalized objects are poisoned until the finalizer actually runs to avoid accidentally touching that payload. In the case of cross-thread handles, these may need to be cleared by a different thread before the finalizer actually runs. In order to clear those references, the slot needs to be unpoisoned. This is issue is ASAN-only and does not affect production or other debug builds.
