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.
