Summary: Turned on the auto formatter. Ran `arc lint --apply-patches --take BLACK **/*.py`. Then run `arc lint` again so some other autofixers like spellchecker etc. looked at the code base. Manually accept the changes whenever they make sense, or use a workaround (ex. changing "dict()" to "dict constructor") where autofix is false positive. Disabled linters on files that are hard (i18n/polib.py) to fix, or less interesting to fix (hgsubversion tests), or cannot be fixed without breaking OSS build (FBPYTHON4). Conflicted linters (test-check-module-imports.t, part of test-check-code.t, test-check-pyflakes.t) are removed or disabled. Duplicated linters (test-check-pyflakes.t, test-check-pylint.t) are removed. An issue of the auto-formatter is lines are no longer guarnateed to be <= 80 chars. But that seems less important comparing with the benefit auto-formatter provides. As we're here, also remove test-check-py3-compat.t, as it is currently broken if `PYTHON3=/bin/python3` is set.
