[clang] Crash when referencing capture in static lambda (#74661)

The constant evaluator could try to reference a lambda capture in a
static lambda call operator. Static lambdas can't have captures, so we
simply abort. Either the lambda needs to be made non-static, or the
capture (and reference to it) need to be removed.
