Handle backend_props removal in PM plugins

[kt474]

Summary

backend_props was removed in Qiskit/qiskit#13706 causing our tests against qiskit main to fail.

In the Qiskit 1.x series, it's required to keep passing on this argument, so it shouldn't be removed until the minimum requirement is Qiskit 2.0. If you want to support both, we should add the argument only if the Qiskit version is in the 1.x series, so something like:

if is_qiskit_1():
    legacy_options = {"backend_props": pass_manager_config.backend_properties}
else:
    legacy_options = {}
pm = generate_translation_passmanager(..., **legacy_options)

That said, the removal hasn't been handled very cleanly on the Qiskit side, and it's plausible it'll change a little before release.
