Fixed an issue with the :meth:`.PassManagerConfig.from_backend`
constructor method when it was used with a :class:`~.BackendV1` based
simulator backend. For some simulator backends which did not populate
some optional fields the constructor would error.
Fixed `#9265 <https://github.com/Qiskit/qiskit-terra/issues/9265>`__ and
`#8546 <https://github.com/Qiskit/qiskit-terra/issues/8546>`__
