Avoid lossing precision when scaling frequencies (#12392) (#12416)

* Avoid lossing precision when scaling frequencies

Classes in pulse_instruction.py scale frequency values to GHz by
multipliying `ParameterExpression` with float 1e9. This can lead
to numerical errors on some systems using symengine. Instead, this
scaling can be done multiplying by integer 10**9.

See: https://github.com/Qiskit/qiskit/issues/12359#issuecomment-2104426621

* Add release note
