OpenXR Atoms have no defined types

[Ybalrid]

It seems that these bindings do not do any wrappings of types generated by XR_DEFINE_ATOM();

Those are all maped to ulong*.

It would be nice to use named types in the API calls that refer to them instead, similar to what is done for OpenXR object handles.

For example, XrPath is not a defined type in the bindings. But it is in the C header. See https://registry.khronos.org/OpenXR/specs/1.1/man/html/XrPath.html
