Make the changes to support both video and metadata. This mostly means
tracking both video format and metadata format separately for each video
node, and using vb2_queue_change_type() to change the vb2 queue type
when needed.

Briefly, this means that the user can get/set both video and meta
formats to a single video node. The vb2 queue buffer type will be
changed when the user calls REQBUFS or CREATE_BUFS ioctls. This buffer
type will be then used as the "mode" for the video node when the user
starts the streaming, and based on that either the video or the meta
format will be used.

A bunch of macros are added (node_supports_xxx()), which tell if a node
can support a particular mode, whereas the existing macros
(is_xxx_node()) will tell if the node is currently in a particular mode.
Note that the latter will only work correctly between the start of the
streaming and the end of the streaming, and thus should be only used in
those code paths.

However, as the userspace (libcamera) does not support dual purpose

in a minor preparation for the possible support for streaming from

drm: vc4: Free the dlist alloc immediately if it never hit the hw

atomic_check creates a state, and allocates the dlist memory for
it such that atomic_flush can not fail.

On destroy that dlist allocation was being put in the stale list,
even though it had never been programmed into the hardware,
therefore doing lots of atomic_checks could consume all the dlist
memory and fail.

If the dlist has never been programmed into the hardware, then
free it immediately.

in negative values being written into registers, which caused

to avoid the incorrect rendering.
