Austin Clements f3b5a2bc19 runtime: prevent descheduling while holding rwmutex read lock 
Currently only the rwmutex write lock prevents descheduling. The read
lock does not. This leads to the following situation:

1. A reader acquires the lock and gets descheduled.

2. GOMAXPROCS writers attempt to acquire the lock (or at least one
writer does, followed by readers). This blocks all of the Ps.

3. There is no 3. The descheduled reader never gets to run again
because there are no Ps, so it never releases the lock and the system
deadlocks.

Fix this by preventing descheduling while holding the read lock. This
requires also rewriting TestParallelRWMutexReaders to always create
enough GOMAXPROCS and to use non-blocking operations for
synchronization.

Fixes #20903.
