rp2/machine_timer: Support hard IRQ timer callbacks.
Unlike some boards like stm32, timer callbacks on the rp2 port are
unconditionally dispatched via mp_sched_schedule(), behaving like
soft IRQs with consequent GC jitter and delays.
Add a 'hard' keyword argument to the rp2 Timer constructor and init.
This defaults to False but if it is set True, the timer callback will
be dispatched in hard IRQ context rather than queued.
