Fixed an issue in scheduling of circuits with clbits operations, e.g. measurements,
conditional gates, updating
:class:`~qiskit.transpiler.passes.ASAPSchedule`,
:class:`~qiskit.transpiler.passes.ALAPSchedule`, and
:class:`~qiskit.transpiler.passes.AlignMeasures`.
The updated schedulers assume all clbits I/O operations take no time,
``measure`` writes the measured value to a clbit at the end, and
``c_if`` reads the conditional value in clbit(s) at the beginning.
Fixed `#7006 <https://github.com/Qiskit/qiskit-terra/issues/7006>`__.
