BUG: _can_use_numexpr fails when passed large Series
This fixes a regression introduced in #27145 where _can_use_numexpr would fail if passed a Series and not a DataFrame. I decided not to use run_arithmetic in the test_suite because there is a separate issue when running floordiv that is out of the scope of the fix. I will open a separate issue in improving the test coverage of "test_expressions.py" as it currently does not check any of the arguments you can pass to the operators, such as 'axis', 'level' and 'fill_value'.

- [x] closes #27636 
- [x] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry

There was some CI failures (Looked like some unrelated http exceptions so I pulled the latest commits in from master to see if that fixes it). 

I have added the xfail for axis=1 on floordiv and made the whatsnew entry more specific now which should now cover all comments. I think the CI error is unrelated.  Can you rebase and see if it resolves itself? > I think the CI error is unrelated. Can you rebase and see if it resolves itself?

That has fixed it. @WillAyd are you comfortable with the changes? Hi @WillAyd is the Whatsnew entry ok now? FYI, can you just merge master & do a regular push, rather than a force push? We don't always get notifications on force pushes. This should also close #27853 @ccharlesgb can you make sure the use case there is covered by the new tests? > This should also close #27853 @ccharlesgb can you make sure the use case there is covered by the new tests?

@jbrockmendel yes this case is covered in the test as long as divide/div and truediv are all still aliases of each other? > FYI, can you just merge master & do a regular push, rather than a force push? We don't always get notifications on force pushes.

@jbrockmendel Had to rebase as the CI was failing again. But I think everything is addressed now. Thanks @ccharlesgb!
