yuzu qt: Add an Apply button to configuration dialogs

Most of the code already exists to do this, but the Apply button itself
was never added. This adds a button and boolean that tells yuzu to save
the configuration after applying settings, even if close/Cancel is
pressed on the dialog. Changes after applying will not be saved when
Cancel is pressed, though.
