Centralize `io` tests into the `test_io` module so they are easier to find and work on. This will make it easier to split `test_general` which takes 30+ seconds in a debug build on my machine. This renames `test_bufio` to be `test_bufferedio` so that it matches the implementation file name (`bufferedio.c`). Validation performed: Tests are run in parallel after change: ```bash ./python.exe -m test test_io -uall,largefile,extralargefile -M12G -j8 ``` Docstring reformat in `test_io/__init__.py` looks reasonable: ```python >>> import test.test_io >>> help(test.test_io) ``` Co-authored-by: Adam Turner <9087854+AA-Turner@users.noreply.github.com>
