[X86] Move the 2 byte VEX optimization for MOV instructions back to the X86AsmParser::processInstruction where it used to be. Block when {vex3} prefix is present.

Years ago I moved this to an InstAlias using VR128H/VR128L. But now that we support {vex3} pseudo prefix, we need to block the optimization when it is set to match gas behavior.
