* Simplify encoder code and clean up keymaps.
-Removed overly complex VIA encoder code. It wasn't adding any value and was confusing users who were trying to customize encoder functionality on VIA keymaps.
-Replaced KC_TILDE with KC_HOME in all keymaps, as KC_TILDE sends a left shift, which was confusing some folks as they tested their build.
-Move layer names to enum
* Change encoder_update_kb to encoder_update_user per PR feedback
