Remove entangler map test

[ElePT]

Summary

This PR removes the entangler map test, which used to test the entangler_map utilities in qiskit.utils and was probably kept under the algorithm tests for historical reasons. These utilities are soon to be removed in Qiskit 1.0 and not really used anywhere in qiskit_algorithms, so I believe that this test can be removed without further consequence.
