Make case style consistent in resource_response.h

The primary motivation of CL is that the function names aren't
consistent within resource_response.h
(e.g."HttpHeaderField" and "ClearHTTPHeaderField").

This CL renames function |ClearHTTPHeaderField| to
|ClearHttpHeaderField| and ports other dependent files to refer to a
new function name.
