Advanced Diagram support: Move class DiagramData to svx AFAP

Splitted and moved parts of DiagramData class to svx as peparation
to access from there. Done as pure virtual class so that no
incarnations will be possible, also made the constructor protected.
The derived class in oox hosts all functionality/data which
involves usage/modification of oox::Shape class. That way we get
closer to get the Diagram DataModel isloated/seperated.
Not-yet moved is the String/Text holding data, it's still in oox.
Moving that one will be next, that will allow to migrate quite
some more functionalty to svx.
