pw_sync_threadx: Disable thread switching in the ISL

Updates the pw::sync::InterruptSpinLock implementation for ThreadX
to disable thread switching if not in an interrupt by raising the
preemption threshold. This way there's no risk that the current
thread gets switched out to another which recursively attempts to
grab the same lock.

This also changes the internal state to use a plain bool instead
of an atomic bool as an atomic is not necessary.
