Update quantum matrix to support both AVR and Chibios ARM (#3968)
* Update quantum matrix to support both AVR and Chibios ARM - Addition of STM32 pin definitions - Created abstruction layer defines to control GPIO (This is a bit pointless for Chibios as we are creating a PAL ontop of a PAL but it is necessary for uniformity with AVR) - Modified matrix.c to use the above functions * minor ifdef fix * Rename of functions and docs - Added documentation. - Renamed functions according to Jack's spec. * Massdrop fix * Update matrix.c * Update quantum.h * Update quantum.h * Update quantum.h * Update internals_gpio_control.md
