Add support for WDK consumption

Has the WDK been implemented in CsWin32?

[AArnott]

We haven't tried it yet. The architecture allows for the WDK metadata nuget package to be consumed by CsWin32 and emitted as C#, but we have never tested it. That's what this issue is about.

FYI in the latest update I removed NtCreateFile from the SDK metadata and moved it to the WDK metadata per https://github.com/microsoft/wdkmetadata/issues/15.

You'll need to support the WDK metadata to support this and other Nt- APIs, or you may want to add a temporary manual definition of NtCreateFile in the projection in the meantime. The WDK definition is below if you need it.

[DllImport("ntdll.dll", ExactSpelling = true, PreserveSig = false)]
public unsafe static extern NTSTATUS NtCreateFile([Out] HANDLE* FileHandle, [In] FILE_ACCESS_RIGHTS DesiredAccess, [In] OBJECT_ATTRIBUTES* ObjectAttributes, [Out] IO_STATUS_BLOCK* IoStatusBlock, [Optional][In] long* AllocationSize, [In] FILE_FLAGS_AND_ATTRIBUTES FileAttributes, [In] FILE_SHARE_MODE ShareAccess, [In] NTCREATEFILE_CREATE_DISPOSITION CreateDisposition, [In] NTCREATEFILE_CREATE_OPTIONS CreateOptions, [Optional][In][MemorySize(BytesParamIndex = 10)] void* EaBuffer, [In] uint EaLength);

[Flags]
public enum NTCREATEFILE_CREATE_OPTIONS : uint
{
    FILE_DIRECTORY_FILE = 1u,
    FILE_NON_DIRECTORY_FILE = 0x40u,
    FILE_WRITE_THROUGH = 2u,
    FILE_SEQUENTIAL_ONLY = 4u,
    FILE_RANDOM_ACCESS = 0x800u,
    FILE_NO_INTERMEDIATE_BUFFERING = 8u,

    FILE_SYNCHRONOUS_IO_NONALERT = 0x20u,
    FILE_CREATE_TREE_CONNECTION = 0x80u,
    FILE_NO_EA_KNOWLEDGE = 0x200u,

    FILE_SESSION_AWARE = 0x40000u,

}

public enum NTCREATEFILE_CREATE_DISPOSITION : uint

    FILE_OPEN_IF = 3u,

I'm working on this, but completion will depend on https://github.com/microsoft/wdkmetadata/issues/41.
