Drop fallback for PathCchCanonicalizeEx() (GH-16341)

This function is only available as of Windows 8 and Windows Server 2012,
respectively, and thus needed a fallback (albeit a non working one).
However, as of PHP 8.3.0 Windows 8/Server 2012 is required anyway, so
we can drop the fallback as well as the dynamic loading in favor of
linking to the import library.
