hrtimers: Introduce hrtimer_setup_sleeper_on_stack()

The hrtimer_init*() API is replaced by hrtimer_setup*() variants to
initialize the timer including the callback function at once.

hrtimer_init_sleeper_on_stack() does not need user to setup the callback
function separately, so a new variant would not be strictly necessary.

Nonetheless, to keep the naming convention consistent, introduce
hrtimer_setup_sleeper_on_stack(). hrtimer_init_on_stack() will be removed
once all users are converted.
