Disable default case checks on clang 18

Recent updates in CI have upgraded clang to clang-18, which gripes when
it finds a switch statement without a default case.  We should add those
cases in, but since we have a lot of those, and CI is currently failing,
disable the check until we get them fixed up

Fixes #24739
