Build mypyc wheels for CPython 3.11 (#3276)

Bumps cibuildwheel from 2.8.1 to 2.10.0 which has 3.11 building enabled
by default. Unfortunately mypyc errors out on 3.11:

src/black/files.py:29:9: error: Name "tomllib" already defined (by an import)  [no-redef]

... so we have to also hide the fallback import of tomli on older 3.11
alphas from mypy[c].
