[toranj] add test to cover OT/NCP SLAAC module behavior (#3688)
This commit updates and renames the existing `test-026-slaac-address` to indicate that it covers the behavior of `wpantund` related to SLAAC address management (in `test-026` we disable NCP SLAAC module). It adds a new test `test-030-slaac-address-ncp` to cover behavior of OpenThread/NCP SLAAC module: - Verify that adding prefix (with SLAAC flag) causes a corresponding SLAAC IPv6 address to be added. - Verify that removing the prefix would remove the SLAAC address. - Verify behavior when same prefix is added and removed on multiple nodes (with or without SLAAC flag). - Check behavior when an IPv6 address with the same prefix already exists. - Check behavior when the address with same prefix is removed (SLAAC module should add a SLAAC address upon removal of the address). - Verify that removal of prefix does not remove user-added addresses with same prefix. - Verify disabling SLAAC module removes any previously added SLAAC addresses, and re-enabling it adds them back (with same IID). - Check behavior when prefix is added while SLAAC module is disabled and then enabled later.
