Shader visible descriptors occupy GPU resource and there are hardware limits. Thus, in order to minimize the amount of shader visible heaps, only non shader visible descriptor heap (staging) will be held by d3d12memory. Then converter will copy the staging descriptor to shader visible descriptor heap per draw. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5875>
