* Hide GstCudaMemory member variables * Make GstCudaAllocator object GstCudaContext independent * Set offset/stride of memory correctly via video meta * Drop GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT support. This implementation actually does not support custom alignment because we allocate device memory via cuMemAllocPitch of which alignment is almost uncontrollable Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1834>
