Add keybindings to switch to ws from all monitors

[Lythenas]

Gnome 44 port of #645

Fixes #635

Adds two new keybindings:

Switch to workspace below (ws from all monitors)
Switch to workspace above (ws from all monitors)

by default they have no keys bound.

They work the same as "Switch to workspace below/above (ws only from current monitor)" (renamed from just "Switch to workspace below/above"). Except the user can switch to all workspaces (except the once currently active on another monitor).

Please test this.

@jtaala btw during testing I noticed that the workspace indicator on the secondary display looked strange. But I don't think this has anything to do with this PR.

Thanks @Lythenas. I'm trying to find the issue where something similar was mentioned when using custom styles (so might not be like here) and using workspace colours (not the default gnome shell background).

Looks good to me. Tested and appears to work well!

Nice job!

Hey @Lythenas have approved. Feel free to merge when ready.

You appear to be using custom styling? (just looks like it since the window selection is an orange colour instead of the default blue). If so, can you share the styling? or might it be another extension (like blur-my-shell or just-perfection etc.?).

@jtaala I can't merge. So feel free to merge yourself. It says:

The base branch restricts merging to authorized users

Regarding your question: I can't find a user.css in the VM where I tested. Also no other extension is enabled, only PaperWM and Ubuntu AppIndicators. I think I just changed the color in the gnome settings (but maybe it was the default):

No dang it - I fixed this (but for develop branch) - forgot about gnome branches.

Okay, should have fixed it for gnome branches. I'll merge anyways.
