Refactor: Move Win32-specific DPI logic to Win32DPIUtils

[ShahzaibIbrahim]

This commit introduces a dedicated Win32DPIUtils class to isolate Win32-specific DPI logic, improving platform separation and maintainability.

This PR:

• Remove all the usages of autoScale methods in windows.

• Move the scaleDown/Up method to windows specific DPIUtil

• Move Win32 DPIUtil related test to Win32 DPIUtil test class.

• Required: Refactor: Move GTK-specific DPI logic to GtkDPIUtil #2280

There are quite few changes in this PR. Could you please split it into several commits so I can review better? Try to split the commits where you used automated refactorings and mention "made by using only automated refactoring 'xyz'" in the commit-text.

There are also compile errors.
