Add definition for NT 5.2/XP x64/Server 2003

[K4sum1]

I noticed QT used to have a separate definition for NT 5.2 and it was used here in previous QT source.

qt/qtbase@a75d42e#diff-171a71294769ce715f7cad90b7d993a802335ab2dc64d98c45873c777ca94124L2044-L2065

I replaced it with just XP thinking it was the same.

However I went back and checked, and the patch only accounts for NT 5.1. I'm not sure if I should make a separate 2003 descriptor or bump the definition for XP to 5.2. Or something else idk.

I realized I could just do this for that instance
