gh-150579: use lazy imports for concurrent.futures#150585

This module has a manual lazy import hack using `__getattr__`. Now that lazy imports exist and cannot be disabled, this could use lazy imports instead. Key differences: this will now show up in sys.lazy_modules when accessed. Error messages should be a bit better without the wrapper `__getattr__` involved. That's the only differences I can think of.
