Window Walker: bring window (from results) onto active desktop

### Description of the new feature / enhancement

Give the ability to bring any found window (from Window Walker results) to the currently active desktop.

### Scenario when this would be used?

Typically, I use about 5 desktops (workspaces). A few windows are showing across all desktops, but most not. It'd be faster to be able to bring any given window to the current desktop I'm on, instead of going to that Window's desktop and having to drag it to the desired desktop.

I have not tried the workspace feature yet. so apologies if it does such, but this is a feature I think would greatly enhance usability and productivity. I suffer from ADHD, and too often I get "sidetracked" when I'm forced to "context switch" to a desktop out of my current focus (ex: supposed to work, but switched to "Fun" desktop where I see that cool cat video posted on FB ;-)).

### Supporting information

Since there are modifiers to actions to take on selected result (enter -> switch to, ctrl+enter -> close), maybe shift+enter -> bring here ?

Start by locating Window Walker's result actions and the workspace or desktop-handling code. Determine how an action can move the selected window to the currently active desktop, then verify that the proposed modifier action brings the window here without changing the intended behavior of existing actions.
