Subject: RGB Matrix: Custom effects on a kb/user level (#5338)

* Revamped custom effects approach

See docs for example usage

* push-up RGB Matrix default mode

Override default effect using RGB_MATRIX_STARTUP_MODE.
Useful on boards without EEPROM support
(*cough* Massdrop ALT/CTRL *cough*)

* update docs
