fix: reach adjacent displays instead of switching workspaces

[Xeus-CC]

A few fixes for directional focus/move on stacked multi display setups (diff PR (#2150) on cosmic-settings with the toggles).

Current focus behaviour is that: from window B or C, using super + down arrow (change focus) targeting window D (which is in another monitor) moves me to another workspace. The expected behaviour is that window D is focused.
Same kind of thing for moving windows. Attempting to move window B down and next to window D, moves window B in a new workspace and it lands on monitor A. The expected behaviour is that it moves next to window D.

The PR fixes the things listed above and a few nice to have things:

• moves that fall through, enter from the opposite edge, like a continuous strip effect.
• added config for controlling which action (move or focus) result in a workspace change.

The current behaviour has been super annoying and I started looking into fixing this myself when I discovered your PR. Thank you very much for your work on this and I really hope your PR gets merged soon!

No worries at all! It would even be super cool if you can test it out yourself too!

Clone and Build

git clone https://github.com/Xeus-CC/cosmic-comp.git
cd cosmic-comp

cargo build --release

Backup and Install

sudo cp /usr/bin/cosmic-comp /usr/bin/cosmic-comp.bak
sudo install -m755 target/release/cosmic-comp /usr/bin/cosmic-comp

Log out and back in. If you want play around beyond default settings, you can do it through here:
~/.config/cosmic/com.system76.CosmicComp/v1/workspaces

Here's my preferred configuration. Moving focus does not result in a workspace change, even if I moved beyond the edge. But, moving windows over the edge does though.

(
    workspace_mode: Global,
    workspace_layout: Vertical,
    action_on_typing: r#None,
    workspace_wraparound: false,
    focus_edge_navigation: LockedSpaces,
    move_edge_navigation: SwitchWorkspace,
)

Thanks very much for the installation instructions! I've tested it out, it works perfectly! I set move_edge_navigation to LockedSpaces as well, so that the moving windows behaves the same way as moving focus. IMHO, moving focus/windows and moving workspaces are semantically different, and should not have been conflated in the first place. After all, there is already a separate default keyboard shortcut for focusing the next/previous workspace (Super+Ctrl+j/k).

Glad it works! Hopefully it gets reviewed and merged soon.
