K.O.Y and German layout for several boards (#14991)

* Added accent.

* Added keymap for 5x6 dactyl manuform on KOY layout

* Added xd75 folder that is not in the main repo anymore?

* Added keymap for naked48 on KOY layout

* Added keymap for splitreus62 on KOY layout

* Added keymap for Dactyl Manuform 4x6 with RGB LEDs and K.O,Y layout

* Fixed error where handedness was not correctly determined because of combining vbus pins of both controllers.

* Replaced dynamic macros bith backspace and delete.

* Changed detecting handedness from detecting usb communication to checking a wired pin. This avoids problems when booting the PC, where VBUS is already high, but no communication is happening -> both halves think they are not master.

* Update keyboards/handwired/dactyl_manuform/4x6/keymaps/scheiklp/rules.mk
