Initial support for d3d11 texture so that encoder can copy upstream d3d11 texture into encoder's own texture pool without downloading memory. This implementation requires MFTEnum2() API for creating MFT (Media Foundation Transform) object for specific GPU but the API is Windows 10 desktop only. So UWP is not target of this change. See also https://docs.microsoft.com/en-us/windows/win32/api/mfapi/nf-mfapi-mftenum2 Note that, for MF plugin to be able to support old OS versions without breakage, this commit will load MFTEnum2() symbol by using g_module_open() Summary of required system environment: - Needs Windows 10 (probably at least RS 1 update) - GPU should support ExtendedNV12SharedTextureSupported feature - Desktop application only (UWP is not supported yet) Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1903>
