Add fusions for re-designed Phi-3 vision and Phi-3.5 vision ONNX models (#22026)

### Description
This PR adds the optimizer logic to fuse the newly designed exported
ONNX models for Phi-3 vision and Phi-3.5 vision.

### Motivation and Context
After the re-designed export of Phi-3 vision and Phi-3.5 vision, the
ONNX models for the vision component and embedding component contain
`If` and `Loop` ops to handle multi-image support.
