When targeting WinRT (WINAPI_FAMILY=WINAPI_FAMILY_APP), the D3D11
types and headers are available, but the DXVA2 ones aren't. This
makes builds of dxva2_*.o to fail, since they both rely on the same
common parameter structs.

This disables the D3D11 VA when targeting WinRT for now. If those
structs really are to be used, we can override the WINAPI_FAMILY
define at the start of the files that need it.

I will be testing Windows Phone decoding in the coming days. I will
let you know if these structures are needed, ie if decoding works.
According to MSDN the decoding API is available on Windows Phone/RT so
it should work.
