Fix timeout in pdf_cpdf_tounicodemap_fuzzer

Iterating through a range of multimap to check for duplicate
cid-unicode mappings can be too time consuming and cause timeout in
CPDF_ToUnicodeMap::InsertIntoMultimap(). This CL changes `m_Multimap`
into std::map<uint32_t, std::set<uint32_t>> so that no duplicate
unicode can be inserted into the set by default and the insertion can
be done more efficiently to avoid timeout.
