With the aim of getting consistency, and removing the need to learn an
additional term, replace uses of uPy/uPython with MPy/MicroPython.
Rule of thumb was to use "MPy" abbreviation where "CPy" is used nearby, but
the full word MicroPython otherwise.

This adds the Python files in the tests/ directory to be formatted with
./tools/codeformat.py. The basics/ subdirectory is excluded for now so we
aren't changing too much at once.
In a few places `# fmt: off`/`# fmt: on` was used where the code had
special formatting for readability or where the test was actually testing
the specific formatting.
