[PATCH v3 0/1] MR11398: dxgi: Fail D3D11_CREATE_DEVICE_VIDEO_SUPPORT until support (bug #50277)

[Stian Low (＠stianlow)]

Fix for UnityPlayer.dll calls to D3D11_CREATE_DEVICE_VIDEO_SUPPORT until supported.

Forces UnityPlayer.dll software video decoding which skips all the cross-device multi-thread calls involving dxgi_resource_GetSharedHandle and d3d11_device_OpenSharedResource.
