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.

(https://dev.azure.com/aiinfra/Lotus/_build/results?buildId=279301&view=results)
The root cause might be the conflicts between different python version.
The inherent python in onebranch image is python 3.9.7.
