1.Add a CI Job on Kind for WireGuard e2e testing

2.Add e2e test for WireGuard-Based Traffic Encryption for Source to Egress Traffic Verify that WireGuard tunnels are set up correctly between the source and the Egress Node Ensure that traffic from the source to egress node is encrypted For more details refer #6190 ( 2nd part will be covered in #6190 fix )

Hi @rajnkamr I think the e2e for WireGuard enablement is more than Egress related. We want to make sure to add a new CI job on Kind, which would check all necessary e2e test cases when the WireGuard is enabled. That would be the top priority. I believe @tnqn would add some e2e test cases as well when he fix the issue #6190. Then @jainpulkit22 can include that part as well later when it's ready.

There are couple of e2e test failures when wireguard encryption is enabled 1.ReconcileGatewayRoutesOnStartup e2e ( #7097 ) 2.traceflow e2e test ( #7096 )
