iso-tester: test with large CIS_ID and invalid CIG_ID/CIS_ID

Add test with a large CIS_ID and multiple CIS so it hits an error
condition in current kernels (which is why the AC configuration is
used).

Add tests for invalid configurations with bad or duplicate IDs, and for
trying to connect two CIS in same CIG without BT_DEFER_SETUP.
