  Occasional release assert failure in EventListenerMap::clearEntriesForTearDown

Reviewed by Chris Dumez.

When a GC thread sweeps an event target, the release assertion in
releaseAssertOrSetThreadUID() could fail as the thread ID will not match.

Allow a GC thread to tear down EventTarget used in another thread.

No new tests since we don't have a reliable reproduction.
