[AMDGPU][True16][CodeGen] true16 isel pattern for fma_mix_f16/bf16 (#159648)
This patch includes:
1. fma_mix inst takes fp16 type as input, but place the operand in
vgpr32. Update selector to insert vgpr32 for true16 mode if necessary.
2. fma_mix inst returns fp16 type as output, but place the vdst in
vgpr32. Create a fma_mix_t16 pesudo inst for isel pattern, and lower it
to mix_lo/hi in the mc lowering pass.
These stop isel from emitting illegal `vgpr32 = COPY vgpr16` and improve
code quality
