qt: Fix leaked dialogs

Some dialogs are allocated on heap but not freed when the dialog
boxes are closed. This means one dialog instance is leaked each
time opened/closed. Also dialogs being subclasses of
GeometryStateDialog means they might lack a parent reference and
are not automatically freed on application shutdown either.

Fix these leaks by letting the dialogs automatically destroy
themselves on close (via WA_DeleteOnClose).

Capture filter, display filter and capture interfaces dialogs are
also leaked on application shutdown. These dialogs are protected by
a NULL check that at least prevent multiple instances. Though
none of them are freed on application shutdown. Fix leaks by
freeing when main window is destroyed.
