[T-Embed-CC1101] Encoder RGB LED Support

[rouing]

Related: #562

This is a draft request, do not merge yet.

I am using this to checkpoint milestones.

Im opening this up for merge since it provides original functionality. This is not a complete feature and will still be tracked in #562 with further pull requests.

This does function as intended on the T-Embed-CC1101
The Menu Option can be found in Others > LED Control (Color), LED Brightness (Brightness)

It does not save state. You must set it on powerup.

Wouldn't it be better to use the LED_TYPE as condition instead of T-EMBED? ( I'm trying to remove as much Device related MACROS from the ./src/ files and make it as generic as possible)

Otherwise we would need to add more devices in here when we could be declaring this MACRO on platformio.ini..

I would suggest to use like:

#if LED_TYPE==WS2812B
   #define LED_ORDER GRB
   #define LED_TYPE_IS_RGBW 0
   #define LED_COUNT 8
#elif LED_TYPE==SK6812
   #define LED_ORDER RGB
   #define LED_TYPE_IS_RGBW 1
   #define LED_COUNT 1
#endif

and in cardputer/platformio.ini add -DLED_TYPE=SK6812 after -DHAS_RGB_LED=1
and in t-embed/platformio.ini add -DLED_TYPE=WS2812B

if other LED models compatible with FastLED come, we can just make the proper setup in the platformio

Pending #571 merge to fix up the flags

Resuming work on this.
