Ricky Stewart 02a7b4ebdf Bug 1654103: Standardize on Black for Python code in mozilla-central.
Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.

To produce this patch I did all of the following:

1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.

2. Run ./mach lint --linter black --fix

3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.

4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.

5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).
