Tolerate removed/replaced CMakeCache.txt with old CMakeFiles/
Users or scripts commonly remove or replace `CMakeCache.txt` without
also removing `CMakeFiles/`. In this case the information saved in the
cache from platform information initialization is missing, so we need to
re-initialize it. In such a case, remove the platform information
directory so that re-initialization will occur and restore needed
information to the cache.
Closes: #14820
