Add CoreML support for to_edge_transform_and_lower

[metascroy]

CoreML supports many ATen ops that decomposed during to_edge (e.g., SDPA, pixel_unshuffle, etc.)

To prevent that users can instead use to_edge_transform_and_lower, but CoreML partitioner did not support that flow. This PR adds support.

Test plan:
New coreml partitioner test.
