RGB Matrix support for Massdrop CTRL/ALT (#5328)

* port Massdrop CTRL/ALT to use RGB Matrix

Co-authored-by: Matt Schneeberger <helluvamatt@gmail.com>

* 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
