selftests: bonding: re-format bond option tests

To improve the testing process for bond options, A new bond topology lib
is added to our testing setup. The current option_prio.sh file will be
renamed to bond_options.sh so that all bonding options can be tested here.
Specifically, for priority testing, we will run all tests using modes
1, 5, and 6. These changes will help us streamline the testing process
and ensure that our bond options are rigorously evaluated.
