Detecting whether Krita comes from a store

[Alvin Wong]

There is a bit of such code in 
https://invent.kde.org/graphics/krita/-/blob/89ccdfb467fe0d68c26b9cc54dde272b66967253/libs/ui/KisWelcomePageWidget.cpp#L229-244, 
for Windows and Linux.

Note that `KisWindowsPackageUtils::isRunningInPackage()` only detects 
whether Krita is installed as a package, it doesn't tell if it is really 
installed from the Store or just installed with the MSIX file. But we 
don't provide signed MSIX to users at least for now, so that should be 
acceptable. (There appears to be WinRT APIs to check for a Windows Store 
license, but calling them can be a bit tricky so I won't try that now.)

Cheers,
Alvin

So, for each store we need to have a way to figure out if it's a store version of Krita. (I forgot what the rules were on the Android Store, but we still have the small donation link, so the support request might be fine?)
