Allow passing Math-specific options to PDF export

The options present in the Math' Print dialog:
* Contents:
- Title;
- Formula text;
- Borders;
* Size:
- Original size;
- Fit to page;
- Scaling N%

were previously not handled in math_pdf_Export. This change makes
them handled, similar to handling of other modules' options.

The final handling of them happens in SmDocShell::Impl_Print.

TitleRow (boolean; default = true)
FormulaText (boolean; default = true)
Border (boolean; default = true)
PrintFormat (long: 0 - original size; 1 - fit to page; 2 - scaling to PrintScale; default = 0)
PrintScale (unsigned short; default = 100)

They are also available in command line, as implemented in commit
0c3b8792b712e939d2ad524d554f96616b4844be (PDF export: allow setting
filter data keys from the cmdline, 2022-01-24), using JSON syntax.

TODO: make these options available in Math' PDF export dialog.
