Make Swap Hands use PROGMEM (#12284)
This converts the array that the Swap Hands feature uses to use PROGMEM,
and to read from that array, as such. Since this array never changes at
runtime, there is no reason to keep it in memory. Especially for AVR
boards, as memory is a precious resource.

tmk_core/common/action.c: refactor for code size; merge multiple cases into one (#11943)
* tmk_core/common/report.h: define `enum mouse_buttons` in terms of `#define MOUSE_BTN_MASK()`

* tmk_core/common/action.c: collapse multiple `case KC_MS_BTN[1-8]:` into single `MOUSE_BTN_MASK(action.key.code - KC_MS_BTN1)`

We all love tapping on our keyboards but this is taking the piss.

This saves ~134 bytes on my ATmega32.
