Refactor ParsedContentHeaderFieldParameters and related classes

This is a preliminary change for implementing charset replacement in
XHR on top of ParsedContentType.

This CL
 - Adds iterator getters for ParsedContentHeaderFieldParameters.
 - Makes ParsedContentHeaderFieldParameters a list of parameters
   instead of a dictionary.
 - Holds unmodified header names instead of lowered names.
 - Removes is_valid_ from ParsedContentHeaderFieldParameters, and adds
   the boolean (as part of Optional) to its holders.
 - Removed Mode::kStrict which can be checked after the parameters are
   parsed.
