tdf#62728 add PDF/A-2 support, change UI default to use that

Browse Source 
There was not much missing to make LibreOffice export valid PDF/A-2,
so let's add that, and switch the UI to use that instead of A-1.

The old PDF/A-1 feature is still accessible via UNO / filter
parameter 'SelectPdfVersion':

- 1 gives you PDF/A-1a
- 2 gives you PDF/A-2b
- 16 gives you PDF 1.6
