[PATCH v2] python: bump minimum requirements so they are compatible with 3.12

[PATCH v2] python: bump minimum requirements so they are compatible with 3.12

[Paolo Bonzini]

There are several Python 3.12 issues in QEMU's python/ directory, but
a particularly problematic one when debugging them is that one cannot
even use minreqs.txt in a Python 3.12 virtual environment to test with
locked package versions.

Bump the mypy and wrapt versions to fix this, while remaining
within the realm of versions compatible with Python 3.7.

This requires a workaround for a mypy false positive

    qemu/qmp/qmp_tui.py:350: error: Non-overlapping equality check (left operand type: "Literal[Runstate.DISCONNECTING]", right operand type: "Literal[Runstate.IDLE]")  [comparison-overlap]

where mypy does not realize that self.disconnect() could change
the value of self.runstate.

The remaining issues are due to missing support for Python 3.12
in released versions of flake8 and pylint, which should be
related to https://github.com/PyCQA/pycodestyle/issues/1145 and
https://github.com/pylint-dev/astroid/issues/2201 respectively.

        v1->v2: switch to the python-qemu-qmp fix for the mypy issue,
                which however requires merging the two patches into
                one for bisectability
