Replacement for https://github.com/pop-os/cosmic-comp/pull/1687, that
works correctly with multiple outputs.
We don't want another window to show a focus indicator while a window is
being dragged, so keep the window in the focus stack. If a window is
being moved out of a stack, change the focus from the stack to the
window.
`refresh_focus_stack()` doesn't seem to be called here, but for good
measure, make sure that calling that function also won't remove a
`CosmicMapped` from the focus stack if it is currently part of a move
grab for the seat.
`Action::Close` already used the keyboard focus target, but some other
bindings didn't. Presumably it's most intuitive if all "current window"
key bindings affect the window with keyboard focus.
These used the focus stack on the `focused_output()` (the one with
keyboard focus), so I guess the main impact is when the keyboard target
is a window being dragged? Then the binding will operate on that window,
or have no effect.
This seems related to some of the behaviors discussed in
https://github.com/pop-os/cosmic-comp/issues/453.
This seems like the correct way to use an `IndexSet`. It shouldn't be
possible to have multiple entries that match, since it's a "set".
We can't define `Borrow<CosmicMapped> for FocusTarget`, so the blanket
impl of `indexmap::Equivalent` won't work, but implementing seems fine.
This is a first use of the new hooks system, which allows customizing
cosmic-comp at compile-time.
In this case, the view() function of CosmicWindow / CosmicStack is
hooked and the hook can change what is rendered as the header bar.

Tested on `SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS=1 supertux2`, using
XWayland. If the game starts with fullscreen configured, it minimizes
immediately on start. But after this change, this no longer happens.
This hopefully will improve behaviors with various X11/wine fullscreen
clients. It may fix
https://github.com/pop-os/cosmic-comp/issues/1510, though looking at the
video the behavior there may be a bit different.
The `id` is defined to be sent only once, on creation of the handle or
later. And only for workspaces that are "likely to be stable across
multiple sessions".
Set we add an `id` initially for pinned workspaces, and add one when the
workspace is pinned.
The `id` is not supposed to be human readable, so we just use a random
value.
It doesn't seem like there's really a need to have `Err(_)` and `Ok(None)`.
`Err(_)` means the set exists for the output, but doesn't have the
appropriate workspace index. It's a bit odd that the set not even
existing becomes `Ok(None)`.
Instead, just return `Err(InvalidWorkspaceIndex)` in either case.
