vkd3d-shader/hlsl: Move default values indexing fixup to the tpf writer stage.

Browse Source 
The primary goal here is to move compilation profile type and version
check outside of a parsing stage. Default values for parameters were
never subjected to this fixup, and it does look tpf-specific, so moving
it where it belongs.
