rust: sync: make doctests compilable/testable

Rust documentation tests are going to be build/run-tested
with the KUnit integration added in a future patch, thus
update them to make them compilable/testable so that we
may start enforcing it.

rust: lock: add Guard::do_unlocked

It releases the lock, executes some function provided by the caller,
then reacquires the lock. This is preparation for the implementation of
condvars, which will sleep after between unlocking and relocking.

We need an explicit `relock` method for primitives like `SpinLock` that
have an irqsave variant: we use the guard state to determine if the lock
was originally acquired with the regular `lock` function or
`lock_irqsave`.

rust: lock: introduce SpinLock

This is the `spinlock_t` lock backend and allows Rust code to use the
kernel spinlock idiomatically.
