* Massdrop lighting support working
This commit is to get the Massdrop lighting code working again through use of the compilation define USE_MASSDROP_CONFIGURATOR added to a keymap's rules.mk.
Added keymaps for both CTRL and ALT named default_md and mac_md. These should be used if the Massdrop style lighting is desired.
* Updating config based on testing results with patrickmt & compile errors
* Updates for PR5328
For CTRL and ALT:
Moved location of new RGB Matrix macros from config_led.h to config.h.
Added RGB_MATRIX_LED_FLUSH_LIMIT (time between flushes) to config.h for correct LED driver update timing.
Re-added missing breathing code for when Massdrop configurator mode is defined.
* remove prilik keymap form PR
Renamed keyboard alt67 to alt and adjusted necessary files where alt67 appeared.
CTRL keymap fixed enum structure name.
usb2422 removed stray define no longer used.
