[Merge to 54] Add observer for BAAnnots from Javascript

This Cl moves the observer code from the CPDFSDK_Widget up into the
CPDFSDK_Annot base class and then adds a second observer for CPDFSDK_BAAnnot
objects.

This allows us to attach an observer to the Annot javascript class which will
update its internal pointer to the BAAnnot if the BAAnnot is destroyed by
the CPDFSDK_PageView being destroyed.
