tests: net: tcp: Add test for FIN,ACK received after final data
Add a test case for a scenario where the final data sent by one peer is
acknowledged in the FIN,ACK response from the other peer. Verify that
the acknowledgment is handled correctly, and a consecutive sequence
number sent by the TCP stack in such case is set correctly.
This complements the other existing test for FIN packet handling, which
verified that data received in a FIN packet is handled correctly. With
those tests in place it should be safer to update any logic related to
FIN packet handling.
