python-common: update tox.ini linting environments

Update the tox.ini environments that lint the sources by splitting the
old lint env into one that just runs flake8 and another that runs the
rstcheck tool. I strongly dislike envs that do more than one thing and
make it hard to check specific files.

Additionally, the main point of this change was to drop the old
`requirements-lint.txt` requirements file that specified an extremely
old version of flake8 that did not work correctly with python 3.12.  The
flake8 of src/pybind/mgr was not pinned so we now match that behavior in
src/python-common, which is heavily used by the mgr modules.

Part of an effort to get ceph tox environments passing on Python 3.12.
