[cr139] Fix access to CreateCookieOptions

There is an override, namely, `URLRequestHttpJob::CreateCookieOptions`,
which is used to capture all calls to `CreateCookieOptions` declared in
the TUs annonymous namespace, and adding extra operations to it. This
override has recently broken as the annonymous namespace was moved into
the `net` namespace.

This change creates a trampoline function to allow the override we have
in `URLRequestHttpJob`, which has the same name, to call
`CreateCookieOptions` through this middle function with a differing
name.

    net: Avoid unnecessary string construction

    Fix a few places in //net where std::strings were constructed
    unnecessarily.

    Also inline the string constants in //net/http/http_auth_scheme.h so the
    compiler can optimize them more easily.

    Also wrap all of url_request_http_job.cc in namespace net and remove
    unnecessary namespace qualifiers from that file.

    Also use base::flat_set instead of std::set for sets that are always
    small.
