This is an attempt to move the sd::Annotation to the common code
in the svx module. This will need to be done in multiple steps so
the first one is to introduce sdr::annotation::Annotation class in
svx module, which is derived by sd::Annotation. Non-problematic
functionality and members are also moved to the svx Annotation.
