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
