tmk_core/common/action.c: refactor for code size; merge multiple cases into one (#11943)

Browse Source 
* 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.
