[tests] remove obsolete DUA-dependent backbone tests (#13141)
This commit removes the obsolete Backbone Router (BBR) certification tests: - tests/scripts/thread-cert/backbone/bbr_5_11_01.py - tests/scripts/thread-cert/backbone/ test_mlr_multicast_routing_across_thread_pans.py These tests are removed because DUA (Domain Unicast Address) routing features (specifically DUA ND Proxying) have been deprecated and removed from the codebase. Since these features are no longer supported, the corresponding certification and validation tests are no longer valid or runnable.
