Cocoa plugin: make sure popups' collection behavior knows about spaces 

It is possible to have several desktops on macOS, and even more - assign
an app to one particular desktop. Then, moving such an app to a different
desktop and using Qt's widgets like combobox may result in a strange
behavior: since it's not a native 'combo button', we create a popup
to show contents (list of items) of Qt's combobox and this popup
may open on a 'wrong' desktop (the one to which the app is assigned to).
To address this, combine the existing collection behavior for popups
with NSWindowCollectionBehaviorMoveToActiveSpace.

Pick-to: 6.6 6.5
Fixes: QTBUG-113507
