Tweak CrashRecoveryContextCleanup to provide an easy method for clients to select between 'delete' and 'destructor' cleanups, and allow the destructor of CrashRecoveryContextCleanupRegister to be pseudo re-entrant.

Tweak CrashRecoveryContext::GetCurrent() to return quickly if 'gCrsahRecoveryEnabled' is false. This avoids us needing to go to thread local storage for
...
the performance sensitive case where we are compiling code.

CrashRecoveryContext: Add missing return, so that the signal fires after we our

routine is off the stack. Otherwise we show up rather confusingly in the stack
trace.

CrashRecoveryContext: Add a simple POSIX implementation.
...
- This works, but won't handle crashes on stack overflow, or signals delivered
to a thread other than the one that crashed. The latter is particular annoying
on Darwin, because SIGABRT tends to go to the main thread.

Support: Add CrashRecoveryContext helper object.
...
- Designed as a simple wrapper to allow clients to attempt to catch crashes
(memory errors, assertion violations, etc.) and do some kind of recovery.
- Currently doesn't actually attempt to catch crashes.
