Release Mach port rights
https://bugs.webkit.org/show_bug.cgi?id=321354
rdar://184386480
Reviewed by Mark Lam.
Several code sites are leaking mach port rights incorrectly.
1. mach_thread_self() retains Mach port rights. Let's just use
pthread_mach_thread_np(pthread_self()), which does not need to retain
it.
2. catch_mach_exception_raise_state_identity_protected receives the task
ID token. When routine succeeds, we need to release the ownership.
3. ResourceUsageThread leaked a mach_thread_self(). Adopt it into a
MachSendRight instead.
