cmake: Avoid '-E tar' failure to extract symlinks on Windows (#13251)
If a symlink fails to extract and the host system is Windows then report
a warning and skip the entry instead of failing. This will allow
archives containing symbolic links to be extracted on Windows with
somewhat gracefully degraded behavior.
