GetFontSize for Variable Text Annotations.
Part of feature work to make Pdfium more usable by mobile platforms that
wish to render comboboxes and textfields using custom displays. Will
return Tf font size for the annotation if applicable. This is obtained
from CPDFSDK_Widget because it is not guaranteed to be set on
CPDF_FormField which only sets font information if DR entry is present.
