What does this Pull Request accomplish?

Removed the nidcpower system_test test_create_and_delete_advanced_sequence_attribute_enum_with_converter test as it is no longer valid for NI-DCPower 2022 Q4 runtime.

In NI-DCPower 2022 Q4, lcr_impedence_autorange is no longer a valid attribute for advanced sequences, but there isn't another advanced sequence attribute in NI-DCPower that uses an enum converter.

List issues fixed by this Pull Request below, if any.

• Internal PR#347032 where lcr_impedence_autorange was made invalid for advanced sequences

What testing has been done?

Relying on the PR to validate the system tests are still valid.

It turns out that the only enums found to have converters in _converters.py are isolation_state and lcr_impedence_autorange. At this point, neither of those attributes is listable (advanced sequences don't support them). I would either comment the test out until we have a new attribute which fits the bill or delete it altogether.

I deleted it.
