Changes here are:
- Split out string format module sub-test to a separate test file, so it
can be skipped on targets that don't have str% capabilities.
- Print the whole type instead of `.__name__` to support targets that don't
have `.__name__` enabled (this still tests the same thing).
- Print `RuntimeError` exception message to be sure the correct exception
is being raised.
This test now runs on unix and zephyr minimal configurations.

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.
