[Keymap] Add userspace and personal keymaps (#7093)

* Add Planck keymap and custom keycodes to userspace

* Add Preonic keymap and extract common ortho layers and keycodes

* Add Leaf60 WKL keymap

* Add M60-A keymap

* Add Levinson keymap

* Fix links in personal readmes

* Use flash target

* Remove duplicate definition

* Remove superfluous line endings

* Planck and preonic encoder should have the same behavior

* Use higher level API
