[UI] Add ways to collect all windows spawn by a particular parent

[tbkoay]

When one connects to more than one vehicle and each spawns multiple child windows. It could get confused to know which window belongs to which vehicle. Suggest the followings

• Provide a button to collect all windows spawned by a vehicle.
• Provide a close button to close all windows spawned by a vehicle.
• Indicate vehicle info at the windows

Existing work, added for completeness of tracking.

Priority: HIGH

Does the first point("Provide a button to collect all windows spawned by a vehicle.") indicate that the windows must come into focus(in front of other windows)?

[tbkoay]

Yes. That would allow us to see all the relevant windows of this particular vehicle.
