Allow QuicConnection to own its QuicPacketWriter

Added a new "bool owns_writer" parameter to the QuicConnection

Also cleaned up the ownership semantics in a number of tests --
previously, the writer was not actually outliving the connection.

QuicConnection::ProcessValidatedPacket doesn't need to be public because
it is only called by QuicConnection::OnPacketHeader.
