performance issue with qiskit 1.0

[Zhaoyilunnn]

In qiskit, StatePreparation is treated as an instruction, and state vector is treated as parameters.
There are many parameter checking logic in qiskit.

In the initial version, I have extracted initialize as an independent module and modified some source code to avoid this issue.

However, after upgrading to qiskit 1.0, I find this difficult to extract because initialize is tightly coupled with QuantumCircuit, and some logic in append can cause issue.
