[AMDGPU][True16][MC] update vop1 mc test with update script (#119778)

This is a NFC change. Update gfx11/gfx12 vop1 test file with the latest
update_mc_test_script.py.

Changing the runline of gfx12_asm_vop1.s since llvm.cfg cannot be read
by the update script.

This is also preparing for the up-coming true16 change.
