v4l2codecs: decoders: Add DMA_DRM caps support
In order to simplify caps negotiations for clients and, notably, be more compatible with va* decoders. Crucially this allows clients to know ahead of time whether buffers will actually be DMABufs. Similar to GstVaBaseDec we only announce system memory caps if the peer has ANY caps. Further more, and again like va decoders, we fail in `decide_allocation()` if DMA_DRM caps are used without VideoMeta. Apart from buggy peers this can happen e.g. when a peer with ANY caps is used in combination with caps filters. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5890>
