This fixes an issue with `cosmic-panel` where, when a workspace is moved
back to an output after a monitor is disconnected and reconnected, the
panel doesn't hide because `cosmic-panel` thinks no toplevel is open on
that monitor.
After some testing, it seems `output_enter` isn't being sent here. In
particular, the `output_leave` call happens before the client binds the
`wl_output`, so there is no `wl_output` to send in an event yet.
This is addressed by keeping track of a set of `wl_output`s that we have
sent the event to. So if an output is bound, `refresh` can add it to
this list and send the event.
This is not needed for workspaces (though it could be done similarly)
since the handle objects are created by server events. So no race should
occur as long as the workspaces global is bound before the toplevel info
one.
- The idea behind sticky don't work well in my language and is probably misleading about the functionality. I opted for zakrywające okna, because it's always on top, but maybe someone will find better allegory for that kind of functionality later on. Also, stack isn't really good to translate, i opted for karta(tab), because it's what the stack is. It might be not the best translation, but i feel it's more natural.
- Fixed stack terminology, based on feedback and contemporary wording in similar software.
This is increasingly not just related to screencopy, so it's weird to
add there. I don't see any other module that fits, so add one called
"quirks" (like the Linux kernel uses for device-specific handling in
generic drives).
This allows `cosmic-workspaces` to rely on cosmic-comp for rendering the
background, and just have transparency. This should be a more reliable
and performant way of doing things, at least for now.
Instead of adding another opaque bool argument, this defines an
`ElementFilter` enum, which makes calls more readable.
Window surfaces are still included in screencopy, as needed for the
workspace previews.

We want this to apply to changes to workspace either through keybindings
or the cosmic-workspaces UI, so it adding a check here seems reasonable.
In principle it could be good to have some kind of privileged protocol
for setting things like this.
We may also want a configuration option to disable animations at some
point.
`(w_elements, p_elements)` tuples are used in a bunch of places. A
struct with named fields is generally an improvement just due to the
fact the order is non-obvious.
But we can also add methods. In particular,
`extend_from_workspace_elements` abstracts out some of the more
redundant code in `workspace_elements`.
It would be nice to avoid allocation everywhere, but iterators would
complicate lifetimes, run into issues with needing multiple mutable
borrows to things like the `Renderer`, and be awkward in certain
functions without generator syntax. In any case, cosmic-comp already
relies on allocating vectors here.
If this abstraction is commonly useful in compositors, perhaps it could
be moved to Smithay.
