Decide how to handle peer-provided active_connection_id_limit transport param Limit

[toidiu]

Pr https://github.com/awslabs/s2n-quic/pull/1043 adds the active_connection_id_limit transport param to the ClientHello.

This value was previously loaded from the peer-provided Limits: https://github.com/awslabs/s2n-quic/blob/main/quic/s2n-quic-core/src/transport/parameters/mod.rs#L1343. However the peer-provided limits also doesnt make sense since the value in the peer_id_registry is hardcoded to 3

Determine:

• should the peer-provided active_connection_id_limit or the hardcoded value be used for the transport param
• what value should be used for peer_id_registry
• if unused, should active_connection_id_limit be removed from Limits
