RGB matrix effect - left-right gradient (#7742) 

* Left-right gradient.

* Update the comment to match the new functionality.

* CPP does integer division so this round is not necessary.

* The x-range is actually 224, update comment and use bit-shifting again.

* Update docs with gradient left-right effect and associated "DISABLE" option.
