use python 3.9.7 in windowai packaging pipeline (#14766)

### Description
Use python3.9.7 in windowsAI packaging pipeline.


### Motivation and Context
In WindowsAI packaging pipeline, cdpxwin1809 is deprecated and it will
no longer be cached from March 2023.

I used the recommended image
[onebranch.azurecr.io/windows/ltsc2019/vse2022:latest](https://onebranch.visualstudio.com/OneBranch/_wiki/wikis/OneBranch.wiki/4587/Container-Images?anchor=recommendation-for-windows-container-image-userst)
But it always failed to pass arm32 jobs. 
It's very likely a regression in VS2022. 
One user reported a similar issue #14190. 
I've submitted a bug to visual studio.
https://developercommunity.visualstudio.com/t/Compilation-Error-with-VS2022-ARM/10285309.

For `onebranch.azurecr.io/windows/ltsc2019/vse2019:latest`, there's an
exception` Error : init_sys_streams: can't initialize sys standard
streams`
It could be solved by updating from python3.7 to python3.9 in the
pipeline.

The root cause might be the conflicts between different python version.
The inherent python in onebranch image is python 3.9.7.
