refactor keypad to share more code
This saves 444 bytes on the pygamer build (both commits taken together)

testing performed:
 * pygamer (samd51) with ShiftRegisterKeys
 * macropad (rp2040) with Keys
 * UM feather s2 (esp32-s2) with KeyMatrix

Result:
 * all ports still worked nicely
 * keys held down at start always registered (>2 trials all boards, >100 trials esp32-s2)
 * keys held down are immediately registered after reset() (>100 trials esp32-s2)
 * double .reset() is OK, accessing .events throws (only tested esp32-s2)
