ICMP: Fix conversation lines for error packets

At the packet list pane, the conversation line between a data packet and its related ICMP error response (timeout, no route,) is not behaving ideally.

Add a conversation table to track the Transport Layer conversations related to ICMP error packets. Update the following protocols to handle this feature: UDP, TCP.

Both deinterlacing strategies (historical behavior with no deinterlacing at all, and any deinterlacing key) are implemented accordingly.

Fix #18636 (closed)
