Resolve `windows py 311` `3221225477 ` exit code

[scbedd]

Example Build

This occurs when adding python 3.12 to the build matrix, as py 311 now runs on windows instead of ubuntu. metricsadvisor and tables both have failures collecting the test run. The actual parallel tox invocation SUCCEEDS. It's just that we're getting a weird exit code due to access violations somewhere.

Need to chase this down or make a determination to ignore the problem.

After resolving, remove eng/pipelines/templates/stages/platform-matrix-metricsadvisor_tables.json.
EDIT: This is being used in communication CI now as well.

Adding some context. I created a basic tox.ini at the root of azure-schemaregistry. It looks like this:

# This tox file is intended for use with any generic development feed. The only requirement is that the development feed
# contain azure* prefixed packages. It does this by assuming that `PIP_INDEX_URL` environment variable is set to target the dev feed
# specifically. Notice that in the [testenv] config, we explicitly set PIP_EXTRA_INDEX_URL to pypi.

# In all cases, whenever we install an azure-* package from a requirement (read: not a specific file), the only source will be from the dev feed.
# once we've downloaded these dependencies, only then do we install other packages from pypi.
[tox]
requires=
  # Ensure that we're running a version of tox compatible with this config
  # 4.4.10 is the lower bound because it incorporates a fix for a bug with `--root`:
  #    https://github.com/tox-dev/tox/pull/2962
  tox>=4.4.10
# note that this envlist is the default set of environments that will run if a target environment is not selected.

This is extremely cut down from what the real tox.ini does. Invoke against it by

tox -r -e whl --root .

Invoking this basic utilization against azure-schemaregistry repros the problem on a local windows install running python 3.11.

However, azure-template does not trip this same behavior. I am currently running subsets of tests to try to locate the feature that is causing this to throw.

Rebalanced the matrix to avoid hitting this issue. Resolving.
