extmod/asyncio/uasyncio.py: Add backwards-compatible uasyncio alias.

This allows existing code that does `import uasyncio` or
`import uasyncio as asyncio` to continue working.

It uses the same lazy-loading as asyncio to prevent loading of unused
features.

This work was funded through GitHub Sponsors.
