summary:
gh-138013: Remove load_tests in test_io.test_general (#138771)
Rely on default test discovery.
Validation:
```bash
# Run before commit
./python -m test test_io -uall,walltime,largefile,cpu,extralargefile -M25G -o
--fail-env-changed -j0 --list-cases | sort > old_cases.txt
# Run after commit
./python -m test test_io -uall,walltime,largefile,cpu,extralargefile -M25G -o
--fail-env-changed -j0 --list-cases | sort > new_cases.txt
diff new_cases.txt old_cases.
# <outputs no changes in case list>
```
