[PATCH 00/19] qapi: statically type schema.py

[John Snow <jsnow@redhat.com>]

Hi! This branch has some comical name like python-qapi-cleanup-pt6-v2
but, simply, it finishes what I started and statically types all of the
QAPI generator code.

GitLab CI: https://gitlab.com/jsnow/qemu/-/pipelines/1074124051

Patch 1 is an actual fix,
Patch 2 is a minor patch for pylint with no runtime effect,
Patches 3-15 fix individual typing issues that have some runtime effect.
Patch 16 adds typing information,
Patch 17 removes the schema.py exemption from the mypy conf,
Patches 18-19 are optional.

Most of the patches (expect 16) are very small. I'm sure we'll need to
rework parts of this, but hey, gotta start somewhere.
