Android: Delete parent window in QtView instead of just the child view

Browse Source 
Since the parent window wraps the QtView, it should always be destroyed
when the QtView is, and live inside QtView rather than the delegate.

Destroying the parent window will always destroy the child window, so
do not destroy the child window separately.

Move createRootWindow and deleteWindow native functions to QtView.

Fixes: QTBUG-124908
