cmake: Stop pointing users at logs on configure errors

Since commit 18e1bfbb3c (cmake: On configure error suggest looking at
CMake*.log files, 2013-07-09, v2.8.12~210^2), when configuring a project
fails, we print `See also .../CMake{Output,Error}.log` near the end of
the output.  This was intended to help users find failures in system and
compiler inspection checks, but for normal project errors the messages
may be misleading.  The logs may contain incidental errors that are part
of normal operation and do not need to be addressed by the user.

Since commit f6ed2585e5 (Modules: Record system inspection steps in the
configure log, 2023-01-16), CMake's builtin modules no longer log
information to the old-style `CMake{Output,Error}.log` files anyway,
so stop mentioning them.

Fixes: #22131
Issue: #23200
