HLSL: Type sanitization: create non-IO types for var decl and fn param/ret

Browse Source 
This introduces parallel types for IO-type containing aggregates used as
non-entry point function parameters or return types, or declared as variables.
Further uses of the same original type will share the same sanitized deep
structure.

This is intended to be used with the wrap-entry-point branch.
