extmod/uasyncio: Get addr and bind server socket before creating task. Currently when using uasyncio.start_server() the socket configuration is done inside a uasyncio.create_task() background function. If the address and port are already in use however this throws an OSError which cannot be cleanly caught behind the create_task(). This commit moves the getaddrinfo and socket binding to the start_server() function, and only creates the task if that succeeds. This means that any OSError from the initial socket configuration is propagated directly up the call stack, compatible with CPython behaviour. See #7444.

extmod/asyncio/stream.py: Fix cancellation handling of start_server. The following code: server = await asyncio.start_server(...) async with server: ... code that raises ... would lose the original exception because the server's task would not have had a chance to be scheduled yet, and so awaiting the task in wait_closed would raise the cancellation instead of the original exception. Additionally, ensures that explicitly cancelling the parent task delivers the cancellation correctly (previously was masked by the server loop), now this only happens if the server was closed, not when the task was cancelled.
