force WINAPI_FAMILY to WINAPI_FAMILY_DESKTOP_APP to be able to use dxva.h
The struct definitions in dxva.h, which are necessary in order to actually use d3d11va, are hidden when WINAPI_FAMILY targets Windows Phone or WindowsRT. Building with WINAPI_FAMILY=WINAPI_FAMILY_DESKTOP_APP is disallowed when targeting ARM. ("Compiling Desktop applications for the ARM platform is not supported.") So we set _CRT_BUILD_DESKTOP_APP to 0 to tell the runtime not to detect some issues with this mismatching. The same tweaks to detect if the API is available is done in dxva2_internal.h when compiling each DXVA2/D3D11VA decoders. Signed-off-by: Martin Storsjö <martin@martin.st>
