[PATCH v4 0/6] qapi: static typing conversion, pt5c

[John Snow]

This is part five (c), and focuses on sharing strict types between
parser.py and expr.py.

gitlab: https://gitlab.com/jsnow/qemu/-/commits/python-qapi-cleanup-pt5c

Every commit should pass with:
 - `isort -c qapi/`
 - `flake8 qapi/`
 - `pylint --rcfile=qapi/pylintrc qapi/`
 - `mypy --config-file=qapi/mypy.ini qapi/`

V4:
 - Dropped the "split check_exprs" patch
 - Based the QAPIExpression class on Dict[str, object] instead
 - Removed the type workaround patch, which is no longer needed.
 - Added a new patch to fix a problem with Python 3.6 and pylint

V3:
 - Squashed a bunch of patches into the QAPIExpression patch
 - Added a few 'info' locals whenever there were >= 3 usages to help
   minimize some churn
 - Removed some type redundancy from docstrings
 - Brought along the two patches from pt0 that I want merged.
 - Removed 'pexpr' entirely, there's no intermediate state where it's
   needed now.
 - Minor style issues.
