uno: new InteropGrabBag UNO prop in OfficeDocument

Added the new InteropGrabBag property to the OfficeDocument service
and modified the JUnit UNO unit tests for it.

Added specific implementation in the sfx2 module for the SfxBaseModel
class.

Added specific inherited implementations in the sc, sd, starmath and
sw modules for the ScModelObj, SdXImpressDocument, SmModel, and
SwXTextDocument classes.

This new property is intended by now for its usage on preserving OOX's
theming although the aim is to be able to re-create the theming in the
future from saved properties.

It could also be used for preserving other attributes for
interoperability among document formats.
