vkd3d-shader/msl: Implement support for VKD3DSPR_UNDEF registers.

Browse Source 
MSL doesn't seem to have any special handling for undefined values,
differently from SPIR-V. Thus we just emit zeros.

UNDEF registers are sometimes created by the DXIL parser,
for example in sm6_parser_emit_composite_construct().
