`await` keyword support in Debug Console

It would be nice to be able to use the await keyword in the Debug Console when sitting on a breakpoint.

The asyncio module actually has a REPL that supports this in the latest versions of Python:

$ python -m asyncio
asyncio REPL 3.8.5 (default, Aug 18 2020, 11:12:18)
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin
Use "await" directly instead of "asyncio.run()".
Type "help", "copyright", "credits" or "license" for more information.
>>> import asyncio
>>> await asyncio.sleep(5, result="done")
'done'

If it's possible to replicate this in the Debug Console, I think this would be a very welcome feature for the python heads that live in asyncio.

If it's all part of the same system, it would also be nice to await watched variables in the Run & Debug Panel. This area:

Regarding the implementation it might be worth checking out what IPython did to archive top-level awaits in the REPL: https://ipython.readthedocs.io/en/stable/interactive/autoawait.html#internals

Pavel Minaev (@int19h) should we transfer this to debugpy?
