Roll pdfium to eef005055d6aafc2cc6066af37ce47d8b15ec7cd

There is a small API change in a recently-added pdfium API exposed by
this roll, so pdfium_engine.cc is simultaneously updated to match.

This pulls in:
eef0050 Kill scattered extern _PDF_CharType declarations.
a039323 Fix infinite recursion in CPDF_Parser::ParseIndirectObjectAt().
fa370ac Fix test naming in previous commit.
e0bbe4a Fix null crash in CheckTrailer.
af9be4f Add pdfium_embeddertests to BUILD.gn
36faa4a Fix build of pdfium_embeddertest under V8_USE_EXTERNAL_STARTUP_DATA.
219e462 Use IPDF_DataAvail interface to hide CPDF_DataAvail.
83f96a0 Add API tests: NamedDestsByName, DestGetPageIndex.
9dcd7b8 Add tests for GetNamedDests() API.
dc43b32 Use signed long for FPDF_GetNamedDest buffer length.
0185408 Simplify UTF16LE_Encode and add unittest.
