Fixed the return values of FPDFAnnot_Get{Rect|AttachmentPoints}

Currently, FPDFAnnot_Get{Rect|AttachmentPoints} would return BBox if the
annotation's appearance stream is defined, which does not make much
sense to the user since BBox is defined in the form space; upon
rendering, the annotation's position in the device space is solely
defined by its rectangle.

This CL removes references to BBox in FPDFAnnot_Get{Rect|
AttachmentPoints}; instead, they will only return rectangle or
quadpoints as requested. The embedder test is also modified to reflect
this change, and also to demonstrate that an annotation's position is
changed only if its rectangle is changed.
