a61cc1b9 - [AMDGPU][True16][CodeGen] Skip combineDpp with t16 instructions (#128918)

[AMDGPU][True16][CodeGen] Skip combineDpp with t16 instructions (#128918) We only emits v_mov_b32/64_dpp. Don't combine t16 instructions with mov dpp. Update the test inputs to be legal. It is future work to emit v_mov_b16_dpp, and then update GCNDPPCombine to combine it with the 16-bit instructions.
