Replace __CMAKE_DELETE_CACHE_CHANGE_VARS_ with a set of changed
variables in cmState to avoid interference from scripts and simplify
handling of changed variables.
Errors during configure step will block re-configure when the toolchain
file has changed. Downstream errors can be caused by failing in
EnableLanguage without an error, behavior introduced in 7a989ed58a
(CMAKE_TOOLCHAIN_FILE: Detect path changes and reset cache, 2026-06-24).
Errors directly related to a changed toolchain file should be fixed by
using the new one.
Trigger a fatal error when the toolchain file change is detected to
avoid wasteful configure that will be reset anyway, then re-configure
only for that specific case. Avoid re-configuring multiple times.
Fixes: #27867
