This corresponds to vkd3d as of commit
acd3ed97dc8e1ac192b2ec6fc19596831a6b61c6.

The cpp_quoted #include directive is fixed up to match the file
naming outside of vkd3d, renaming the reference to
vkd3d_d3d12sdklayers.h back to d3d12sdklayers.h.

This matches other renamings that are done at the start of the
file for vkd3d renamed idl files as well.
