fix(transpiler): preserve layout in OptimizeSwapBeforeMeasure (#16920)

* fix(transpiler): preserve layout in OptimizeSwapBeforeMeasure

When anonymous qubits preceded registered qubits,
OptimizeSwapBeforeMeasure retargeted measurements to the wrong qubit wires.

Fix this by adding the original qubits and clbits to the newly created
measurement layer.

* Address review comments: link issue, assert circuit equality
