vcl win: Use only Windows build number to identify version

Browse source 
Now that support for Windows versions earlier than Windows 10
was dropped in

    commit b664c08a6d
    Date:   Sat Dec 7 14:46:24 2024 +0500

        Drop support for Windows versions prior to Windows 10

, also drop handling for earlier versions from
`getOSVersionString`.

All still supported Windows versions (10, 11,
corresponding server versions) report a major/minor
version of 10.0 (see [1]), so rely on the build
version only and drop previous logic to retrieve
the major and minor version.
