[Keymap] Added mverteuil keymaps and userspace common code (#7876)

* Added mverteuil content

- Userspace
- Knops keymap
- Preonic keymaps

* Simplified and replaced some magic numbers

* Convert tabs to spaces

* Clean up LED handling, better animation, better layer init

* Use get_highest_layer per @drashna suggestion

* Reorder prototypes/reformat

* Simplified/more expessive and fixed initial layer LED

* Remove changes to git ignored files
