c: Turn -Wincompatible-pointer-types into a permerror
The change to build_conditional_expr drops the downgrade
from a pedwarn to warning for builtins for C99 and later
language dialects. It remains a warning in C89 mode (not
a permerror), as the -std=gnu89 -fno-permissive test shows.

PR c/96284

type mismatches to a permerror.
