net/http: export the "new" error codes from RFC 6585

These were proposed in the RFC over three years ago, then proposed to
be added to Go in https://codereview.appspot.com/7678043/ 2 years and
7 months ago, and the spec hasn't been updated or retracted the whole
time.

Time to export them.

Of note, HTTP/2 uses code 431 (Request Header Fields Too Large).

Updates #12843
