Generated AsyncRequestIdFB does not compile due to undeclared XR_NULL_ASYNC_REQUEST_ID_FB

[KiruyaMomochi]

Current generated headers does not compile. The generated AsyncRequestIdFB struct in openxr_atoms.hpp uses XR_NULL_ASYNC_REQUEST_ID_FB, but this macro is actually not declared in openxr.h.

A quick workaround maybe add a global variable NO_NULL_ATOMS in cpp_generator.py and return 0 for such atoms in computeNullAtom.

hmm, where is it generated?

[KiruyaMomochi]

Sorry for late reply. My "current" means generating C++ projection for the latest (1.0.26) OpenXR SDK source.

The generated AsyncRequestIdFB struct is in file openxr_atoms.hpp.

Hmm, I suspect that instead, we should have such atoms not have a default constructor and those methods that depend on having such a define. 0 is not inherently invalid for this atom, it appears.

Raised an issue on the extension itself because suppressing this is harder than I anticipated.

Compilation fixed in #35 , re-enabled type in #37
