gh-112622: Pass name to loop create_task method (#112623)

This affects task creation through either `asyncio.create_task()` or `TaskGroup.create_task()` -- the redundant call to `task.set_name()` is skipped. We still call `set_name()` when a task factory is involved, because the task factory call signature (unfortunately) doesn't take a `name` argument.
