Add VIA support to MxSS, plus minor tweaks (#7809)

* Add VIA support to mxss and general cleanup * Add support for RGB test for FLEDs * Add LAYOUT_all to allow for more configuration * Remove blank layers * Updated readme * Improve use of EEPROM * Credit where its due * Use the latest iteration of rgblight code * Keep the RGB timer running if the front LED is in RGB mode * Fix RGB breathing animation * Better supported RGB animation Only thing not working is alternating, but that's not too important * Abstract front LED handlers from main kb code * Add support for indicator LED color changing * Remove debug statement * Persist indicator LED colors * Mark custom sections in rgblight.c * Light commenting * Fix up keymaps * Add/update comments * Remove bloat from default hex * Tidy a stray tab * Out with the old, in with the new * Out with the old, in with the new * Add LAYER_STATE_8BIT for VIA keymap
