fix(sync/wait_condition): deadlock in WaitCondition::wait
...
Instead of using a simple switch to determine if preemption is enabled
(`is_preemptable: bool`), a counter is used instead. This handles the
case where a function holding a `PreemptGuard` calls another function
that creates a new `PreemptGuard`.

This is not a perfect solution, since the kernel technically already has
all the information it needs to synchronize this between the kill()
invocation and the time WaitCondition::wait is called, but it should not
have any noticeable performance impact.

Fix UB in the locking code of context switching
...
The spin crate considers it UB to call force_write_unlock while there is
a threads trying to obtain a read lock on the same rwlock.
This also switches to the spinning_lot crate for the context rwlock as
it has support for a write guard keeping a reference to the rwlock using
an Arc instead of a reference.
