cmSystemTools: Fix regression in input path normalization on Windows
Since commit 622596c6b2 (cmSystemTools: Re-implement
ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5) we normalize input paths, while resolving symlinks
only if followed by `..` components, by using `cm::PathResolver`'s
`LogicalPath` mode. However, that approach assumes POSIX semantics for
resolving paths with symlinks and is incorrect on Windows.
On Windows, file system operations naively remove any component
preceding `..` regardless of whether it is a symlink. Prior to the
above commit, `ToNormalizedPathOnDisk` matched that behavior using
`CollapseFullPath` followed by `GetActualCaseForPath`. Restore it using
`cm::PathResolver`'s `CasePath` mode.
