The `usort` config in `pyproject.toml` has no effect due to a typo. Fixing the typo make `usort` do more and generate the changes in the PR. Except `pyproject.toml`, all changes are generated by `lintrunner -a --take UFMT --all-files`.

Fixes#92675
Here we implement a native version of [`einops.rearrange`](https://einops.rocks/api/rearrange/) using first class dims to perform the operations. The string parsing + validation, documentation, and relevant tests are adapted from `einops`. The API is exactly the same as the `einops` API.
The main idea is to take the string and convert it to a left and right `ParsedExpression`, and then find a mapping from the axes to first class dims. Once the mapping exists we convert the left expression `composition` list into a `Tensor.__getitem__` index and the right expression `composition` into the `Tensor.order` arguments, and then use this to dynamically create a callable that performs the `rearrange` operation as specified by the pattern.
