Brad King 9eb8e4b22b Write CMakeCache.txt atomically (#13040) ...

The write code introduced by commit 0b0d1b1d (add CMakeCache.txt
support, 2001-02-22) uses a temporary file but does not replace the
original atomically.  Use cmGeneratedFileStream to do both
copy-if-different and atomic replacement.
