Handle symlinked directories correctly during gn clean on Windows.

Prior to this change, gn clean would recursively delete the contents of
symlinked directories on Windows, which could cause data loss when the
symlink pointed to important directories outside the out/<dir>.

This change adds a check for FILE_ATTRIBUTE_REPARSE_POINT to prevent
recursive deletion of symlinked directories. Now gn clean will only
remove the symlink itself while preserving the contents of the target
directory.
