Merge to XFA: Sanitize CJBig2_SymbolDict's memory usage.

- Use std::vector<JBig2ArithCtx> instead of storing pointers to arrays.
- Make CJBig2_SymbolDict's members private with accessors.
- Use std::vector<JBig2ArithCtx> in related places.
- Steal Chromium's vector_as_array() and use it as an adaptor as needed.
