Subject: [PATCH] Add the ability to disable Music Mode completely (#2339)

* Skip process_music in NO_MUSIC_MODE is defined

* Skip matrix_scan_music if NO_MUSIC_MODE is defined

* Skip music_all_notes_off if NO_MUSIC_MODE is defined

* Leave matrix_scan_music in, because it reduces firmware size by 150b....

* Add docs for NO_MUSIC_MODE

+You can completely disable Music Mode as well. This is useful, if you're pressed for space on your controller.  To disable it, add this to your `confid.h`:

 ## MIDI Functionality
 
 This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile.
