In QUIC, do not re-arm PTO timer on sending application data before handshake gets confirmed.

This change also includes 3 client side only changes:
1) Fix the encryption level of sending PINGs before handshake gets confirmed.
2) Do not postpone PTO alarm on receiving undecryptable packets.
3) Enqueue undecryptable HANDSHAKE packet in 0-RTT connections.
