D3D12CreateDevice requires Win32_Graphics_Direct3D11

[Jasper-Bekkers]

I would've assumed this was a win32metadata issue, but I can't seem to find the cause of this in win32metadata, so posting it here. If it needs to move, let me know.

However it looks like Win32_Graphics_Direct3D11 is required for D3D12CreateDevice because of the D3D_FEATURE_LEVEL enum which is slightly unfortunate (since it's the only thing that seems to require it).

In the regular C++ headers, these enums are defined in d3dcommon.h so they can be shared between versions.

(In looking through this, I also noticed D3D11On12CreateDevice is behind the 12 feature toggle, which seems slightly odd too, I'd expect it to only need 11).

Yes, I believe this is a metadata issue. Will transfer.

I think @damyanp and @sotteson1 have done some work to clean this up but they can confirm. As soon as a build is available with their changes I can ingest into the Windows crate.

@Jasper-Bekkers - if you were looking at win32metadata after #579 was merged then you should see that this problem has been resolved - this PR was intended to solve exactly these sorts of problems.

It doesn't look like there's a release that includes that PR yet.
