[Keyboard] Added Handwired Redragon K552 Kumara (RGB) (#14004)

* Added Handwired Redragon K552 with default and via keymaps

* Resolve some request changes, and change the cols pin to a better one.

* Resolved request changes

* Added OLED support and resolve request change

* Increase polling rate to 1000hz

* Update font for OLED, and change logo

* Added LED Underglow support

* Add personal custom keymap

* Nit some line, to get better way to look on code

* Refactor everything and solved some issue.

* Resolved issue
