Miklos Vajna 619b0b8339 pdfium: update to 7795 
Upstream now has a theoretical build config where the rendering is
handled via skia and not agg; use -DPDF_USE_AGG to keep things
unchanged.

Also it now depends on harfbuzz, use our harfbuzz instead of the bundled
one.

This reverts the:
- vcl/qa/cppunit/VectorGraphicSearchTest.cxx
- vcl/qa/cppunit/PDFiumLibraryTest.cxx
- sw/qa/extras/uiwriter/uiwriter11.cxx
- sc/qa/extras/scpdfexport.cxx
- sd/qa/unit/export-tests.cxx
parts of commit 4731284939ce286316738d1fced7f16e9b91028b (pdfium: update
to 7691, 2026-02-19), since they are not necessary, probably after
pdfium.git commit 4a298961558e1e54fde965d133d61f90df2431bc (Revert
"Reland "Remove character width check from cpdf_textpage.cpp"",
2026-03-10).
