Subject: [PATCH] Python: Fix windows runtime error: adapt asyncio event loop
 policy for windows python 3.10 and above (#1416)

### Motivation and Context
To fix a runtime error on windows for python version 3.10, 3.11 and
above

On windows, python version above 3.10.1, there will be a runtime error
caused by asyncio event loop. add adapting code for windows when python
version is above 3.10.1 to avoid the error.

### Description
<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->

Refer link:

https://docs.python.org/3/library/asyncio-policy.html

"Note In Python versions 3.10.9, 3.11.1 and 3.12 the
[get_event_loop()](https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.get_event_loop)
method of the default asyncio policy emits a
[DeprecationWarning](https://docs.python.org/3/library/exceptions.html#DeprecationWarning)
if there is no running event loop and no current loop is set. In some
future Python release this will become an error."

Note: per testing, this error also occurred on python 3.10 below 3.10.9
