  [X86] Add constant comments for VGF2P8AFFINEQB rmbi forms (#194789)

Handle AVX-512 VGF2P8AFFINEQB rmbi instructions in X86MCInstLower.

Unlike the existing rmi forms, rmbi uses a 64-bit broadcast memory
operand, so the constant pool entry may only contain the broadcast
source instead of a full-width vector constant. Print that constant
repeated across the destination vector width when forming the asm
comment.
