DolphinQt: Save when closing settings window

If Dolphin crashes, changes that have been made to settings are often
lost. This has been a minor annoyance for me when developing, but it has
become a much bigger issue recently due to the problem where Dolphin
freezes on shutdown for ROG Ally users.

Instead of saving the config when certain arbitrary settings are
changed, let's save the config when the user closes the settings window.
