Default feedback only include primary GPU, so the previous version of
this prevents the use of explicit modifiers from the non-default GPU.

or something similar will hopefully improve this at some point...
But we can presumably assume `dmabuf_format` will only include formats
valid to create a dmabuf `wl_buffer` from.
This fixes `BufferConstraints` errors for workspace capture on Nvidia
outputs of a Intel+Nvidia system. (That didn't happen on Amd+Nvidia;
maybe a linear stride alignment issue?)
Workspaces can be pinned, and dragged to reorder or move to a different
output.
These features are enabled only if cosmic-workspace-v2 advertises the
necessary protocol version and capabilities.
The layout of the labels and pin buttons could be tweaked a bit still.
Some hacks and workarounds are needed to get drag and drop working as
desired. Something iced and libcosmic could potentially improve in the
future. But this now seems fairly robust.
Potentially relevant on compositors not advertising this, or if a
compositor wanted to advertise `Activate` support for some but not all
workspaces. This will be more relevant with other capabilities.
This makes the `workspace_bar` more responsive to different child sizes, which enables fixing the size of the smaller dimension of the screencopy, while allowing it to expand unrestricted in the larger dimension (to match the aspect ratio).
This tries to find a split point in the list of toplevels to maximize
the scale factor when calling `RowColToplevelLayout` twice. If it
doesn't get a better scale factor, it just uses a single row/column.
Some things don't seem quite right, but the existing layout is not
perfect, and this can help.
Without the added cross axis spacing, there's overlap, so there may be
something wrong with the requested sizes...
Previous definition assumed the cross axis of a single window would not
need more downscaling than the total main axis of all children. But that
doesn't always work out.
