The test `test/ClangScanDeps/P1689.cppm` was previously not supported on Windows due to the differences in path separators between Windows and Linux. This normalizes the paths, allowing this test to run on Windows as well.

This is motivated by the review feedback for #<!-- -->145221, where the same change was suggested for a test derived from this one.
