[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

+# Redragon K552 Kumara
+
+![K552](https://i.imgur.com/XpNmJpBh.png)
+
+A handwired K552 Kumara. Built using STM32F103RCT6 Mini
+
+* Keyboard Maintainer: [HorrorTroll](https://github.com/HorrorTroll)
+* Hardware Supported: Redragon K552 Kumara and STM32F103RCT6 Mini
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/horrortroll/k552:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (4,6) in the matrix (B key) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
