Add possibility to adjust the font size for PDF form filling

[Pratham Gandhi]

Hey Andy,
I am already working on this. Will try to raise an MR for this by this or
next weekend. If you'd still like to take this up, I can share my progress
with you.
The same issue exists with combo box, list box, etc. Not sure, but some
change could be required on poppler end as well.

Cheers,
Pratham
