all: Rename "sys" module to "usys". This is consistent with the other 'micro' modules and allows implementing additional features in Python via e.g. micropython-lib's sys. Note this is a breaking change (not backwards compatible) for ports which do not enable weak links, as "import sys" must now be replaced with "import usys".

try:
import usys as sys
except ImportError:
import sys
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.

modsys: Add basic sys.exc_info() implementation. The implementation is very basic and non-compliant and provided solely for CPython compatibility. The function itself is bad Python2 heritage, its usage is discouraged.
