USBDEV: invalid_sync

Intersperse valid USB traffic with invalid SYNC signaling. Set up IN and OUT endpoints, stream known traffic while randomly generating invalid noise (without valid SYNC), and verify all valid data transfers succeed while invalid signaling is ignored.

Write a UVM sequence that extends usbdev_base_vseq to verify the above.

Output: /home/dev/workspace/sequences/usbdev_bad_traffic_vseq.sv and /home/dev/workspace/agent_sim_cfg.hjson

Run: /home/dev/scripts/run_test.sh usbdev_invalid_sync
