  [AMDGPU][True16][MC] disable incorrect VOPC t16 instruction (#120271)

The current VOPC t16 instructions are not implemented with the correct
t16 pseudo. Thus the current t16/fake16 instructions are all in fake16
format.

The plan is to remove the incorrect t16 instructions and refactor them.
The first step is to remove them in this patch. The next step will be
updating the t16/fake16 pseudo to the correct format and add back true16
instruction one by one in the upcoming patches.
