Handle construction of string ExtensionArray from lists
I had to add a string-based Arrow Extension array to trigger the bug but did not run the same test suite as we do on the boolean array as I don't see it adding value but just runtime at the moment.

- [x] closes #27673
- [x] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [ ] whatsnew entry
