dzn: Add ABI helpers for D3D12 functions returning structs

The currently available D3D12 API headers have incorrect C function
prototypes for these functions when compiling for non-Windows platforms.

Future changes here will move these helpers into the DirectX-Headers
project, but:
* The process of getting a fix into the headers is still ongoing
* I'd prefer to avoid taking an immediate dependency on just-published
  headers again

So, for now add some helpers to work around this problem in Dozen

+ * structures, the MSVC C++ ABI specifies that they are always called with the return
+ * structure allocated by the caller, and passed as a hidden second parameter,
+ * after "this". But the C compiler doesn't apply that automatically to the C
+ * equivalent definition of the method, and so that ABI needs to be explicitly
+ * embedded in the C function signature. For Linux, no such ABI difference between
+ * C and C++ exists, and so C callers should use the same signature as C++.
