Interactive signing via the .uno:Signature command parameters were
possible, but headless PDF export had no similar parameters.
The primary difference is that the interactive signing works with the
sign certificate of the SfxViewShell, while PDF export has its own
vcl::PDFWriter::PDFWriterContext::SignCertificate.
Fix the problem similar to what commit
80723fccbb (filter: allow PDF export to
sign from the cmdline, 2022-02-03) did, but here we don't refer to an
already configured sign certificate by name, we take the sign cert/key
from parameters instead.
Test this in the NSS case where it's known to work, ignore the mscng
signing case for now.

LibreOffice Filters
Filter registration and some simple filters (also descriptions).
Desperate splitting of code into small shared libraries for historical
reasons presumably (OS/2 and Windows 3.x). The libraries produced from
the code in each subdirectory of filter/source/graphicfilter are
graphic format import or export filters. But they don't have uniform
API. Some have either a GraphicImport or GraphicExport entry point,
and are loaded and used in a uniform fashion from code in
svtools/source/filter/filter.cxx. Others have different API and are
loaded from other places. For instance icgm has ImportCGM, and is
loaded and used by sd/source/filter/cgm/sdcgmfilter.cxx (!).
Svgreader is used for "File -> Open" and then to choose the svg file.
For "Insert -> Picture -> From File", see svgio/source/svgreader directory.
Filter Configuration
The filter configuration consists of two parts, the type definition in
filter/source/config/fragments/types/ and the actual filter definition
in filter/source/config/fragments/filters/.
Each file type e.g. text file should be represented by exactly one type definition. This type can then be referenced by several different filters, e.g. calc text, writer text.
