D3D_COMPILE_STANDARD_FILE_INCLUDE, incorrect constant type

[riverar]

Metadata currently has

public const uint D3D_COMPILE_STANDARD_FILE_INCLUDE = 1u;

Headers (d3dcompiler.h):

// D3D_COMPILE_STANDARD_FILE_INCLUDE can be passed for pInclude in any
// API and indicates that a simple default include handler should be
// used.  The include handler will include files relative to the
// current directory and files relative to the directory of the initial source
// file.  When used with APIs like D3DCompile pSourceName must be a
// file name and the initial relative directory will be derived from it.
#define D3D_COMPILE_STANDARD_FILE_INCLUDE ((ID3DInclude*)(UINT_PTR)1)

UINT_PTR is 32-bit/64-bit depending on target arch.

We could probably do better and associate it with (ID3DInclude*)1 and it should slot in nicely with existing D3DCompileFromFile(..., _In_opt_ ID3DInclude* pInclude, ...)
