tdf#153040 PDF export: disable export of form fields as PDF forms by default

Open <https://bugs.documentfoundation.org/attachment.cgi?id=195586>,
notice that from "bbb", the middle "b" is bold, export to PDF, none of
the "b"s are bold.

The reason for this is that by default we map form controls and content
controls to fillable PDF forms, which can only contain plain text.

Fix the problem by defaulting to not exporting form controls / content
controls to PDF forms: most users just want a PDF that is close to what
they saw in the edit window -- and the ones who want a fillable PDF form
can still opt in. Once the UI checkbox is enabled, we even remember
that.

Based on <https://gerrit.libreoffice.org/c/core/+/152622>, thanks
Justin!
