win: Prefer integers instead of strings for OS version comparison

* Add a WinOSVersionInfo struct holding the major and minor
version and build number for a Windows release.
* Extract a static WinSalInstance::getWinOSVersionInfo from
WinSalInstance::getOSVersion that returns a corresponding
version info.
* Adjust the local getOSVersionString helper to take integers
for major and minor version instead of an "NT version" string
that is a dot-separated version number containing both of these.
* Use WinSalInstance::getWinOSVersionInfo in ImplDrawNativeControl
to compare the major version + build number to identify Windows 11
instead of relying on WinSalInstance::getOSVersion to return
a string starting with "Windows 11".
