dfdfc4e4 - [AMDGPU][True16][Codegen] remove another build_vector pattern from true16 (#149861)

[AMDGPU][True16][Codegen] remove another build_vector pattern from true16 (#149861) Remove another build_vector pattern which takes a i16 but placed in a VGPR_32 from true16 mode. This stop isel from generating illegal "vgpr_32 = COPY vgpr_16". ISel will use vgpr16 build vector pattern in true16 mode instead
