Keyboard: Add new keyboard "Sol" from RGBKB (#4497)

* Add final RGBKB Sol firmware

* Apply suggestions from code review

Apply most of the changes noroadsleft has suggested

Co-Authored-By: Legonut <legonut3@gmail.com>

* Cleanup readme

* Cleanup keymaps per @noroadslefts suggestions

* Remove eeproms, use set_single_persistent_default_layer

* Suggestions from @noroadsleft and @drashna

some small cleanup

* Change RGB_SMOD to RGB_RMOD

* fix RGB_SMOD

* Apply suggestions from code review

Remove redundant lines
