Backlight and RGB now working for JJ50 (#2929)

* Added support for JJ50 from KPRepublic, no rgb or backlight control yet. Added as a layout of ymd96 at the moment (same microprocessor). Basic keymap with three layers to get started.

* Added support for JJ50

* Tidied up jj50 code, backlight and RGB is now working.

* Renaming "KEYMAP" to "LAYOUT" to adhere to the new QMK standards.
