Subject: [PATCH] Add empty test files for test reorganization (#12288)

This PR adds empty test modules that match the "Test Organization" guidelines outlined in the [developer guide](https://github.com/rapidsai/cudf/blob/branch-23.02/docs/cudf/source/developer_guide/testing.md#test-organization). Follow-up PRs will move existing tests into these test modules.

While I have attempted to match the structure of our API reference as much a possible, there are small differences. For example, the API reference lumps together [Reshaping, Sorting, and Transposing](https://docs.rapids.ai/api/cudf/stable/api_docs/dataframe.html#reshaping-sorting-transposing), while I opted to include two different modules for reshaping and sorting.

There are only a couple of instances where I needed to deviate from the structure though.
