QOpenGLWindow example: use std::unique_ptr instead of QScopedPointer

Browse Source 
QScopedPointer is scheduled for deprecation, and can't decide whether
it wants to be a scoped, or a unique pointer.

The use of a unique_ptr members requires that the destructor be
out-of-line, since the payload classes are only forward-declared in
the header file.
