Related: tdf#106972 vcl PDF import: downgrade PDF >= 1.5

There are two problems with these newer PDF versions:

- the current PDF export code doesn't know how to roundtrip such PDF
images (needs work on both the import and export side)
- upgrading the default PDF export version would upset readers who can't
parse PDF >= 1.5

So instead of raising the default PDF export version, for now just be
conservative and depend on pdfium to downgrade the PDF image version to
1.4 if it would be higher.

Given that this modifies the input of the graphic filter this also needs
changes in the ODF export, so that the filter result will contain that
downgraded data, not the original one.
