Remove Qobj input to UnitarySimulatorPy.run

[rupeshknn]

Summary

qiskit.providers.basicaer.UnitarySimulatorPy.run() never deprecated a qiskit.qobj.QasmQobj input and will still support it while the qasm simulator and statevector simulator will not.

#11394 deprecates this functionality in a PR to stable/0.46. This PR to main removes this functionality. Fixes #11046
