Make CPDF_Dictionary methods take CFX_ByteString arguments
This will help avoid duplicate allocation of CFX_ByteStrings when the caller already has one. It may seem counter-intuitive that requiring the caller to pass an allocated CFX_ByteString rather than a static CFX_ByteStringC would improve the situation, but due to the idiosyncrasies of std::map, the CPDF_Dictionary methods must always do an allocation under the covers which can't be avoided. The changed callers in this CL are places where we would previously demote to CFX_ByteStringC and then allocate a a duplicate CFX_ByteString in the dictionary method.
