disinherit OWizardPage and SfxTabPage from vcl TabPage

Now that there's no need to support weld/unwelded mixes of
pages in dialog any more.

inherit from a BuilderPage which contains a Builder and
Toplevel container

BuilderPage Activate and Deactivate replace TabPage ActivatePage and
DeactivatePage, allowing disambiguation wrt SfxTabPage ActivatePage and
DeactivatePage.
