[Feature]: Support exclusive zones on Wayland (panel/dock window type)

[yesrod]

What happened?

When using own_window_type = panel and out_to_wayland = true with conky 1.20.2, the conky window doesn't behave as expected.

Specifically, when another window is maximized, it covers the conky window instead of stopping at the border of the conky window.

I have not tested with versions newer than 1.20.2 because of #1960.

Expected behavior:

• Launch conky with own_window_type = panel and out_to_wayland = true in .conkyrc
• Maximize another window
• The maximized window does not cover the conky window

Actual behavior:

• Launch conky with own_window_type = panel and out_to_wayland = true in .conkyrc
• Maximize another window
• The maximized window covers the entire screen, blocking the conky window entirely

Version

1.20.2

Which OS/distro are you seeing the problem on?

Ubuntu

Currently, Wayland doesn't support conky being displayed anywhere other than behind other windows (i.e. desktop mode).

wlr-layer-shell supports this with zwlr_layer_surface_v1:set_exclusive_zone.

In my case, the issue is present in X11 (openbox), not in wayland (both x11 and wayland backends work in labwc session). The details are:

own_window_type = 'dock'

It seems to be independent of the wayland support, and for some reason, its a change that started in conky > conky-git-1.21.7

In my case, the issue is present in X11 (openbox), not in wayland (both x11 and wayland backends work in labwc session).

@Bluey26 That's a separate issue. Wayland support isn't implemented at all currently, and this issue is solely purposed for tracking that as indicated by the label. Subscribe to a related issue or create a new one.
