Subject: sw content controls, checkbox: add PDF export

Map this to vcl::PDFWriter::CheckBoxWidget, which uses the /FT/Btn
widget, i.e. a (toggle) button which is not a pushbutton or a
radiobutton).

Also avoid a border for content controls: it just cuts out some part of
the rich text/plain text content control filled in text + causes a
double border for checkboxes, so not useful.
