wayland: Refactor dmabuf attributes in linux-dmabuf-v1
At the moment, dmabuf importing is scattered all over the place in kwin. It would be great if we had one function that takes dma-buf attributes and returns an EGLImage if successful.
As the first step, make linux-dmabuf-v1 implementation provide dmabuf attrs compatible with KWin::DmaBufAttributes.
