Investigate Padding interaction with borders and border backgrounds

[ramezgerges]

Current behavior

Currently, the padding on an IBorderInfoProvider is not used to calculate the numbers for the border shape and the border background. A quick attempt found some differences between WinUI and Uno (at least skia) when Padding is added. This should be investigated after https://github.com/unoplatform/uno/pull/16562 merges

This also should take BackgroundSizing property into account

I thought padding is only considered during measure/arrange and shouldn't have any impact elsewhere 😕

@ramezgerges Can you extend the issue for exact scenario that's currently broken?

The BorderVisualClipping sample used to do some weird stuff if you added a Padding to the elements, but I'm testing it now and it seems to be... fine? I will close for now until I find an actual problem.
