_pew: move to common-hal

I noticed that this code was referring to samd-specific functionality,
and isn't enabled except in one samd board (pewpew10).  Move it.

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.
