py/objmodule: Implement PEP 562's __getattr__ for modules. Configurable via MICROPY_MODULE_GETATTR, disabled by default. Among other things __getattr__ for modules can help to build lazy loading / code unloading at runtime.

# test __getattr__ on module
# ensure that does_not_exist doesn't exist to start with
this = __import__(__name__)
try:
this.does_not_exist
assert False
except AttributeError:
pass
# define __getattr__
def __getattr__(attr):
tests: Format all Python code with black, except tests in basics subdir. 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.
