Add transpose copy

[metascroy]

This adds coremltools support for transpose_copy, the copy variant of transpose. Many view ops in coremltools already register the copy variant as an alias, e.g.,

• view: https://github.com/apple/coremltools/blob/main/coremltools/converters/mil/frontend/torch/ops.py#L2316
• permute: https://github.com/apple/coremltools/blob/main/coremltools/converters/mil/frontend/torch/ops.py#L1011

But it looks like for transpose this was missed.

LGTM! Thanks Scott for adding transpose_copy support 🙏

We might need to block merge until our release is done, @TobyRoseman to confirm

Thanks @YifanShenSZ! Can you also have a look at the ExecuTorch PR when you get a chance: pytorch/executorch#12648

CI passed, once @TobyRoseman has finished the release we can land this.
