[clang] [Clang][Sema][Builtins] Check argument count for `__builtin_allow_sanitize_check` (PR #183927)

Given the change in this area I think it's worth going through the full list and see if any other builtins aren't doing the required arg checks, rather than just going through them one by one as they show up in fuzzers and similar.
