Permit scrollable AWT tab pages a la scrolled Dialog

UNO dialogs since LibreOffice 4.0 permitted setting HScroll /
VScroll properties to enable scrolling for too large a content.
Conceptually clone this code over to TabPage as well, and register
necessary UNO properties in the toolkit UNO wrappers.

Add missing API documentation also to UnoControlDialogModel,
plus the new properties to the UnoControlTabPageModel

Layout code really doesn't like any extra controls it didn't create
itself - so create scrollbars only on demand.
