Wilba d7f1e072a8 Added macros to Dynamic Keymaps, Zeal60 RGB backlight improvements (#4520)
* Refactored M6-B to use Zeal60 RGB backlight code

* Fixed M6-B LED co-ordinates

* Minor changes to RGB config for Zeal65

* Added dynamic keymaps to WT80-A, WT60-A, WT-80A, U80-A

* Macro implementation

* Implemented macros, API protocol version 8, RGB backlight fixes

* Improved radial effects for M6-B

* Fixed undefined references when building an RGB keyboard after M6-A
