The dockwidget's toplevel window would be a parent of the container's
window when floating. When plugged back into the mainwindow the
dockwidget's window is destroyed and the container's window along
with it. Added a function toplevelAboutToBeDestroyed to unparent
the containers window before this happens so parentWasChanged will
work correctly.

We change the behavior slightly from the initial implementation in
5.1. Forcing the use of native child widgets is causing massive
performance issues so instead, we attach the embedded QWindow directly
to the root window. The only exception is QScrollArea and QMdiArea
which still enforces native windows for the entire parent chain
to make clipping and stacking work.
