tdf#160293 sc NBB: tabbed groupbar_compact keep tabs in Pivot context

The VBox was hidding each child item since none had
Pivot or any as context types.

This didn't affect any other NBB variants
because they hadn't wrapped the tabs in a ContextVBox.

Using context-any would be bad for PrintPreview for example.
