Extend time out in Windows GPU packaging jobs (#20207)

### Description
Extend Windows GPU Packaging job building time out to 6 hours, and test
stage to 3 hours.



### Motivation and Context
There're still a few timeout issues after refactoring. The probability
is about 20% in
https://dev.azure.com/aiinfra/Lotus/_build?definitionId=84.
I found the building could be finished in 4 hours if it becomes slow,
https://dev.azure.com/aiinfra/Lotus/_build/results?buildId=434340&view=logs&j=0c6ee496-b38e-55a9-3699-12934156e90f,
although in most cases, it only take about 30 minutes.
Not like before, the building couldn't be completed.
So, In this PR, I extend the timeout to 6 hours.

And one interesting thing, if one windows GPU job becomes slow, all
other windows GPU jobs in the same run become slow too.
So I doubt it has something with the ADO or virtualization. That is,
it's not completely random.
