[scripts] update cert tests to use thread_cert.TestCase (#4874)

- Update all test cases to inherit thread_cert.TestCase and update
  topologies accordingly. The topologies should all be correct because
  they are automatically generated, not hand written.

- Use default Thread version: 1.1

- Cleanup node tmp files in tmp directory according to the current
  PORT_OFFSET in setUp. This is required by
  test_reed_address_solicit_rejected.py and test_coap_observe.py since
  they define multiple test functions in one TestCase.

- Removed call to set_extaddr64 because it's not necessary and causing
  failures.
