hrtimer: Move hrtimer_callback_running() to hrtimer_bases.h

The usage of the hrtimer base introduces a dependency on the timer base
structure definitions from the widely-used hrtimer.h.

Move the helper to hrtimer_bases.h to trim this dependency.

Also adapt the two only callers to now include hrtimer_bases.h.
