Add count group flag in windowCount workspace selector prop

[sungyoonc]

Describe your PR, what does it fix/add?

Adds the groupCount workspace selector prop.
The groupCount is the same as the windowCount but it counts groups instead of windows in a workspace.
Resolves #5488

Workspace rules can now do

workspace = g[t1], bordersize:10

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

A comment here shows an example using windowCount with range 0-4. But this is invalid according to the code. Did you meant to make 0-4 a valid range or just typo in the comment?

// w - windowCount: w[0-4] or w[1], optional flag t or f for tiled or floating, e.g. w[t0-1]

if (to < from || to < 1 || from < 1) {
    Debug::log(LOG, "Invalid selector {}", selector);
    return false;
}

Is it ready for merging, or does it need work?

Ready, but wiki mr needed.

why not integrate it with w? w[gt1-2]

How about this?

[vaxerski]

okay, but I don't get why you're doing all that refactoring outside of what you are adding. I'd rather it wasn't there.

[sungyoonc]

Removed all the refactoring bits. Should I make a separate mr or just scrap it?

In the current state, making a window into a group doesn't update other windows in that workspace.

No, they are fine, just unrelated to this MR. Feel free to make it separately

[vaxerski]

can you make a wiki mr?

Hmm, coming back to this now that it is in...

Are there any sets of selectors I can use that match tiled(windows+groups) = ?

(I guess you can kinda do it with multiple workspace rules?)

[sungyoonc]

I think mixed counting flag(non grouped window + groups) need to be added to support that.
