[Keymap] Improvements to KidBrazil keymap to better handle OLED/LED Matrix timeout. (#7688)

* Added KidBrazil custom keymap for CRKBD
-Custom Font
-Custom OLED output

* Added missing readme

* Oled Timeout Update for KidBrazil Keymap (#1)

* Setup Oled timeout based on simple timer

* Cleaned up comments and added timeout for LEDs

* Fixed some small errors

* Updated oled timout with matrix scan

* Updated oled timout with matrix scan

* Update withou eeprom

* Update timer code

* Use process user instead of keymap

* Added ifdef to protect oledtimer

* Updated with half timeout state for logo

* Removed middle tier timer

* Final cleanup of unused files

* Updated code as per suggestions & requests

* Second round of revisions

* Updated keymap to better handle LED timeout
- Added boolean to hold LED state
- Added init function to set rgb to known state
- Modified RGB_TOG to work with noeeprom commands

* Finished adding the timeout for OLED and testing on CRKBD

* Updated documentation

* fixed the timeout logic so it works as intended

* Update keyboards/crkbd/keymaps/kidbrazil/README.md

+## OLED & RGB Matrix timeout
+This keymap will set a automated timeout system for the OLED screen and the RGB
+matrix. After 3 minutes or so the LED screen will display the logo on both
+halves and 5 minutes after that both the LED and the Matrix will be switched
+off.
+
+Once a user hits the keys again, the LED matrix will turn back on unless the
+user has disabled it via RGB_TOG.
+
+## Flashing
+To flash this on your CRKBD simply use the `make crkbd:kidbrazil:flash`
+command.
+
 ### TODO
-- Fix OLED and Backlight so they turn off when the computer sleeps, currently
-  only the left hand does that and the LEDs still stay on.
 - Wait for Spit_common to be implemented in CRKBD and revisit the special color
   layers and animations
