Add python presubmit checks This change adds python type and formatting checks and consolidates code health checks in ./tools/health-check. Dealing with relative imports in python is tricky, so we are making ./tools/impl a proper package with no directly executable files. Some of the bash shorthands in ./tools had to be converted to python for this. To make the new checks pass, we run the formatter and fix some mypy type checks.
