Freeze `Net::HTTP::SSL_IVNAMES`, `Net::HTTPResponse::CODE_CLASS_TO_OBJ`
and `Net::HTTPResponse::CODE_TO_OBJ` to improve Ractor compatibility.

This change allows the following code to work:

    Ractor.new {
      uri = URI.parse('http://example.com')
      http = Net::HTTP.new(uri.host, uri.port)
      http.open_timeout = nil
      http.read_timeout = nil
      http.get('/index.html')
    }
