[dv/aes] connect alert_agent to AES testbench
Connect alert_esc_agent to drive alert_rx responses when alert
triggered.
This is all the code needed to plug in alert receivers in a IP. If
reviewers are okay with the flow, next PR will update the uvmgen to
automatically genenrate the code as much as possible.
