When resuming a TLS session using Dial (and not DialEarly), 0-RTT should
be disabled at the TLS layer, even if the session ticket allows for
0-RTT resumption.
This bug is not critical, since Dial doesn't return an EarlyConnection,
so the client wouldn't be able to actually send 0-RTT data in practice.
This is more consistent with both the RFC and the rest of the API. For
example, the option in the Config is already name EnableDatagrams, and
the property in the ConnectionState is named SupportsDatagrams.

Some of the 10 testing packets are might be lost, while others might be
CE-marked. We need to detect mangling if all testing packets are either
lost are CE-marked.
* ackhandler: detect ECN mangling
Mangling means that a path is re-marking all ECN-marked packets as CE.
* ackhandler: only detect ECN mangling once all testing packets were sent
They were introduced to avoid an import loop in the tests in the logging
package, but the same can be achieved by having a dedicated package for
the tests (logging_test).
* also send session ticket when 0-RTT is disabled for go1.21
* allow session ticket without transport parameters
* do not include transport parameters for non-0RTT session ticket
* remove the test assertion because it is not supported for go1.20
* Update internal/handshake/session_ticket.go

There is no good reason to manually set the validity period for Retry
tokens. Retry tokens are only valid on a single connection during the
handshake, so it makes sense to limit their validity to the configured
handshake timeout.
