[Keymap] Corne keyap with tap dance Swedish support (#6857)

* Adding profile for Corne with tap dance Swedish support.

* Remove extern keymap_config_t keymap_config as no longer needed

* Changed to use tap_code over register_code

* Removed persistent_default_layer_set

* Moved macros to hvp user space ink tap dance code

* Removed not used functions

* Moved to an ifbased include statement

* Removed not needed characters
