[AMDGPU] gfx11 vop3dpp instructions

gfx11 adds the ability to use dpp modifiers on vop3 instructions.
This patch adds machine code layer support for that. The MCCodeEmitter
is changed to use APInt instead of uint64_t to support these wider
instructions.

Patch 16/N for upstreaming of AMDGPU gfx11 architecture

Depends on D126475
