vcl pdfium render: handle widget annotations for form fields

Note that we render the bitmaps without FPDF_ANNOT, so comments are not
rendered into the bitmaps, rather we create them on top of the bitmaps
in Draw, explicitly.

FPDF_FFLDraw() draws content which is already an annotation, but not yet
interactive content; so this just fixes "missing text", as far as the
user is concerned.

Verified that e.g. vcl/qa/cppunit/data/PangramAcrobatAnnotations.pdf
indeed still doesn't render comments into bitmaps after this.
