Add readPort() and some API to 'tmk_core/common/*/gpio.h' (#12754)
* add readPort() and some API to 'tmk_core/common/*/gpio.h' The following macros have been added to gpio.h. * readPort(port) * setPortBitInput(port, bit) * setPortBitInputHigh(port, bit) * setPortBitOutput(port, bit) * writePortBitLow(port, bit) * writePortBitHigh(port, bit) * add data type 'port_data_t' into gpio.h * rename qmk_pin to pin
