wayland: add dwl/mango support

[charlesrocket]

Tested with mango 0.12.4(release)

Closes #457/#51

Wayland protocols are not implemented like this in a qt project. Look at
https://github.com/quickshell-mirror/quickshell/tree/master/src/wayland/hyprland/global_shortcuts for a simple one. We also never check in generated code.

Oh, missed that one! It is not generated tho, just a bespoke implementation 😺

I see how you could potentially miss the QtWayland tooling and qtwaylandscanner but how do you miss wayland-scanner? Nobody does that part by hand

It was pretty late, and DWL spec is not long enough for me to look for easy ways ahah

Partial review:

Can you clarify if tags are functionally per monitor or global? the global tagCount seems to indicate they're global, and if setting client tags via monitor affects global or monitor state?

[outfoxxed]

Undecided on if its OK to merge the implementation and interface on this one

[outfoxxed]

If exposed at all this should probably be attached to toplevel

Also does mango support the ext-workspace protocol? We have a mostly done implementation on a branch that I could fix up and merge, which is strictly an improvement over this protocol.

DWL is all per output

///! A DWL monitor/output with IPC state.
/// Exposes per-monitor compositor state: tag list, active layout, focused
/// window title, app ID, and fullscreen/floating flags.

///! State of a single DWL tag.
/// Represents one tag slot on @@DwlIpcOutput.

Tho tag count and layouts are global.

Looks like it does https://github.com/mangowm/mango/blob/d441ca22f4bd7554f04defdd36f13bedc38610e7/src/ext-protocol/ext-workspace.h

The upcoming release of wlroots0.20 has also integrated the encapsulation support of the ext-workspace protocol. At that time, most compositor will only need little code to use this protocol.

Tested ext-workspace branch, and everything seems to work with Mango. Tho keyboard and window (tiling/grid/etc) layouts are not covered. I could strip the PR to support missing topics only.
