### Summary

Add preflight checks to `lib/ansible/cli/__init__.py` for both the local locale and the fsencoding to ensure they are `UTF-8`, and abort when they are not.

We implicitly require this now, but have never strictly enforced it. Due to using `pathlib` in more places, to avoid undefined behavior in our codebase, due to the utf-8 expectation, check this early and fail fast.

### Issue Type

Feature Idea

### Component Name
```
lib/ansible/cli/__init__.py
```
### Additional Information

We may also need to evaluate the `C` locale.  I know some users are running ansible from devices with only the `C` locale.
