Roll pdfium to eef005055d6aafc2cc6066af37ce47d8b15ec7cd

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.

dc43b32 Use signed long for FPDF_GetNamedDest buffer length.
0185408 Simplify UTF16LE_Encode and add unittest.
