hyprland/workspaces: Add enable-bar-scroll option

[VAWVAW]

This PR adds the option to capture scroll events for hyprland workspaces on the whole bar like it works with sway.

When using this, I had a bug that if I enable bar scroll on both hyprland and sway and put sway/workspaces after hyprland/workspaces in modules-left the bar scroll would no longer work on sway. When putting sway/workspaces first, it works on hyprland and sway. I don't know enough to track this down though.

But why would you use both at the same time? 😄

Hey guys, can we please have this merged, I tested it and I need the functionality. I want to run the upstream version and not my locally built version, so that I get all updates.

MUCHAS GRACIAS @zjeffer and @VAWVAW
I hope I can use this feature soon

I'd like to test this out but there are way too many conflicts since the workspaces.cpp file was split up into two files. Can you fix the conflicts?

I wish I'd found this before writing #3401. There's a small problem with this, in that events will get handled twice.

For example, scrolling on volume modules will both change the volume and workspace. This is probably not ideal.

I rebased the changes (once more) and adapted them to the new way of loading options:
