Add and fix _noeeprom functions to many of the RGB Underglow functions (#3070)

* And and fix _noeeprom functions to many of the RGB Underglow functions

* Many functions are unnecessarily calling the eeprom write code. The toggle/enable is command is especially guilty of this, as it writes to EEPROM 3 times.  But rgb mode writes twice, every time it's called. And init resets the rgb eeprom range and then writes back to it twice!
* Fixed the rgblight_sethsv_noeeprom to work as expected, by moving a lot of the code to a helper function.
* Added a noeeprom function for mode, enable, disable, and toggle functions. (didn't bother for increase/decrease stuff, and didn't add new keycodes)
* Add to predefined colors list
* Add new functions to manual/docs

* Update RGB Sleep feature to use _noeeprom

Because that's exactly what it should be doing, actually!

 Look in `rgblights.h` for all available functions, but if you want to control all or some LEDs your goto functions are:
 
 ```c
-rgblight_disable();  // turn all lights off
-rgblight_enable();  // turn lights on, based on their previous state (stored in EEPROM)
+// turn all lights off (stored in EEPROM)
+rgblight_disable();
+// turn lights on, based on their previous state (stored in EEPROM)
+rgblight_enable(); 
+
+// turn all lights off (not stored in EEPROM)
+rgblight_disable_noeeprom();
+// turn lights on, based on their previous state (not stored in EEPROM)
+rgblight_enable_noeeprom();
+
+// where r/g/b is a number from 0..255.  Turns all the LEDs to this color (ignores mode, not stored in EEPROM). 
+rgblight_setrgb(r, g, b); 
+// HSV color control - h is a value from 0..360 and s/v is a value from 0..255 (stored in EEPROM)
+rgblight_sethsv(h, s, v);

+rgblight_mode_noeeprom(x);
