This is blocked on a TabView v3 from WinUI.

### Tasks
* [ ] Tabs should make a new window as soon as their torn out
* [ ] Torn-out tabs need to be able to snap to snap positions (maximized, snap layouts) without dropping first
* [ ] Multiple tabs can't be dragged/dropped all at once
* [ ] Dragging a tab in a window with a single tab should just drag the window

Uploaded a video to show exactly what I'm talking about. In the video below I'm comparing tab tear out and joining with Microsoft Edge. Windows Terminal's tab experience should be like Edge because it's currently hard to work with it when a tab can't join another window unless that window is visible.
