esp32/machine_timer: Warn that hard timers are not implemented.
machine.Timer() has inconsistent behaviour between ports: some run
callbacks in hard IRQ context whereas others schedule them like soft IRQs.
Most ports now support a hard= argument to the machine.Timer constructor
or initialiser to explicitly choose between these behaviours. However,
esp32 does not support hardware interrupts because they are not delivered
to the main thread, so the interrupt handler would need to acquire the GIL.
Raise a ValueError if hard=True is requested for esp32 machine.Timer.
