annot: new Annotation sdr object, replacing annotation tags

Previously the annotations are shown as annotation (smart) tags,
which just mark in the document the existence of an annotation at
a certain position. For PDF support the annotations can be more
complex, so they can show many forms of vector graphic, ink,
bitmaps, text boxes,... and for this a normal tag is not enough.

This change moves the annotations from simple tag to use the sdr
objects, so any SdrObject can be created as an annotation. The
previous tag annotations are using SdrObject (actually SdrRect)
subclass AnnotationObject and the code that previouslly worked
with the tag annotations has been adapted.

The (PDFium based) PDF import has been changed to use subclasses
of the SdrObjects for the PDF annotations.
