hrtimer: Add cleanup class for on-stack timers
hrtimer_setup_on_stack() requires callers to destroy the timer before its
backing stack storage goes out of scope, but the setup interface does not
encode the required teardown pairing.
Add an hrtimer_on_stack cleanup class that pairs on-stack setup with
destroy_hrtimer_on_stack(). Document the existing setup API's lifetime
requirement.
The cleanup class provides debug-object teardown, not timer
cancellation. Callers must ensure that no hrtimer operation can still
access the timer before the scope ends; in particular, the timer must
no longer be queued and any running callback must have completed.
