* Fix interaction graph vf2 scoring to include 1q component In #9148 a bug was introduced into the vf2 scoring code. In that PR the vf2 passes were changed to treat standalone qubits as a special case to improve the algorithmic efficiency of the pass. However, that PR broke the scoring algorithm so that it was no longer factoring in the 1q component of the interaction graph when scoring a layout. This meant that when scoring a potential layout only the 2q error rates were been factored into the score and the pass was potentially selecting worse performing qubits. This commit fixes this error and ensures the scoring is looking at all the error rates. * Update qiskit/transpiler/passes/layout/vf2_utils.py (cherry picked from commit 0e44c5e)
