UART: loopback
Test system loopback: enable system loopback, drive uart TX and verify data is loopbacked through RX (RDATA equals WDATA). Test line loopback: enable line loopback, drive uart_rx with random data and verify uart_tx has same value (no synchronizer register between them).
Write a UVM sequence that extends uart_base_vseq to verify the above.
Output: /home/dev/workspace/sequences/uart_loopback_vseq.sv and /home/dev/workspace/agent_sim_cfg.hjson
Run: /home/dev/scripts/run_test.sh uart_loopback
