[roll third_party/pigweed] pw_sync/interrupt_spin_lock: Optimize try_lock for uniprocesors
Optimizes the existing backends for InterruptSpinLocks to implement
try_lock through lock, given that the existing uniprocessor backends
do not support SMP and ergo you cannot fail to acquire a lock. The
only risk is that you recursively lock which is already guarded
against by the lock implementation.
Also updates the backends to consistently use debug asserts to
guard against recursive locking.
And lastly it disables some test behavior which relied on recursive
locking which is undefined behavior.
