RFR: 8324879: Platform-specific preferences keys are incorrect for Windows toolkit

Tue Jan 30 00:57:50 UTC 2024

`WinApplication` contains mappings of platform-specific preference keys to platform-independent keys.
These keys are incorrect (for example, `Windows.UIColor.ForegroundColor` instead of `Windows.UIColor.Foreground`).

This was not discovered during testing because the manual test application doesn't show the values of platform-independent properties (it only shows the platform-specific mappings). I've exended the test application to also show the platform-independent property values.
