loplugin:vclwidgets check for assigning from VclPt<T> to T*

Inspired by a recent bug report where we were assigning the result
of VclPtr<T>::Create to a raw pointer.

As a consequence, we also need to change various methods that were
returning newly created Window subclasses via raw pointer, to
instead return those via VclPtr
