eg replace asyncio.create_task with a Task Group
replace wait_for/wait with Timeout/CancelSceop
create a function for asyncio.gather that uses a Task Group

This could use anyio.create_task_group and anyio.CancelScope, but now
there's 3.11 asyncio.TaskGroup and asyncio.Timeout are available.

Obviously I'm biased and think the anyio versions are a better choice, but
it's easier to add asyncio.TaskGroup/Timeout and worry about trio support
in the 'future'.
