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."SetHTTPStatusText" and "HttpStatusText").

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