Let quic::serializedpacket to own the frames and optionally the encrypted_buffer. no behavior change.
This change removes quic::ClearSerializedPacket() and quic::OwningSerializedPacketPointer. Their functionality have be moved to the destructor of quic::SerializedPacket. To simplify ownership, I changed quic::SerializedPacket to move-only and changed many functions in QuicPacketCreator and QuicConnection to take a SerializedPacket object instead of a pointer.
The optional ownership of encrypted_buffer is expressed using the newly added SerializedPacket.release_encrypted_buffer function. Currently only connectivity probing packets are setting it. In the next flag-protected change, I'll use it to free writer-allocated buffers.
