Upgrading Pyre requires updating test fixtures with any upstream changes
to Pyre's query results for the `simple_class.py` fixture.
This adds a new `scripts/` directory to the repo, with a script to
regenerate test fixtures. The script regenerates the cache data fixture,
and updates the `TypeInferenceProvider` tests to use `assertDictEqual`
and helpful error messages for better behavior in future mismatches.
This also includes a slight bump to Pyre 0.9.10 to fix install issues on
Apple Silicon M1 Macs, and regenerated fixtures using the script above.
