ackhandler: implement timer logic for path probe packets (#4940) 
* remove unused bool return value from sentPacketHandler.getPTOTimeAndSpace

* ackhandler: implement timer logic for path probing packets

Path probe packets are treated differently from regular packets: The new
path might have a vastly different RTT than the original path.

Path probe packets are declared lost 1s after they are sent. This value
can be reduced, once implement proper retransmission logic for lost path
probes.

* ackhandler: declare path probes lost on OnLossDetectionTimeout

ackhandler: remove unneeded SetHandshakeConfirmed from SentPacketHandler (#4890) 
According to section 4.9.2 of RFC 9001, dropping the Handshake packet
number spaces happens when the handshake is confirmed.

ackhandler: use a slice to keep track of sent packets (#3841) 
* ackhandler: simplify deletion of old packets in packet history

* ackhandler: use a slice to keep track of sent packets

This is a vastly simpler data structure than the combination of map
and linked list used before. It avoids using a linked list (bad cache
locality) and a sync.Pool (for list elements), as well as having to do
hash table lookups.

In the future, this can be easily replaces with a ring buffer, avoiding
all allocations.

* ackhandler: don't store packets that were declared lost

confirmation of the handshake.
