[nit] Drop `to_from` (and all the variants of that) from function names. The test file already encodes the fact that all tests exercise the `vector.to_elements` + `vector.from_elements` -> `vector.shuffle`.

Also, what are the high-level categories in this test files? I see two:
* genuine shuffle (e.g. `@to_from_elements_single_input_shuffle`)
* concat `@to_from_elements_shuffle_tree_concat_4x8_to_32`
* concat with poison values (e.g. `@to_from_elements_shuffle_tree_concat_3x4_to_12`)

Anything else? If this is correct, it would be good to clarify this split.
