QUIC: refactored packet processing.
- split ngx_quic_process_packet() in two functions with the second one called
ngx_quic_process_payload() in charge of decrypring and handling the payload
- renamed ngx_quic_payload_handler() to ngx_quic_handle_frames()
- moved error cleanup from ngx_quic_input() to ngx_quic_process_payload()
- moved handling closed connection from ngx_quic_handle_frames() to
ngx_quic_process_payload()
- minor fixes
