vkd3d-shader/dxil: Avoid using the I/O signatures from the DXBC container.

Browse Source 
We currently generate our own I/O signatures inside the DXIL parser, but
use the element counts from the DXBC container signatures to allocate
the input_params/output_params/patch_constant_params arrays. That
happens to work for well-behaved inputs, but it's asking for trouble.
