Refactor the crkbd/via keymap and fix OLED bugs (#10354)

* Refactor the crkbd/via keymap and fix OLED bugs

* Revert "Refactor the crkbd/via keymap and fix OLED bugs"

This reverts commit dc9db029fc6b077fc7600b49e920b755c522d100.

* Fix OLED display bugs

* Remove unused functions

* Remove uncessary the key logger

* Add new lines at end of file

* Remove unnecesary extern for is_master

* Remove extern is_master from rev1.h

* Remove ssd1306 from common dir because its the legacy lib

* Update default keymap based the via keymap

* Remove foostan keymap because it will be legacy

* Revert Remove unnecesary extern for is_master

* Remove unnecessary backslashes.
