After this change, we correctly increment the offset by the next switch case type. Before this change, we accidentally incremented the offset by `functions()` size instead of `cpp_overload_sets()` size and vice versa. Also sorted the switch cases according to the order of the enum, for consistency. This might help prevent a future similar incident. This fix prevents crashing in the newly introduced test `multiple_too_few_args_calls`. This also has the side effect of showing `null name` for `cpp_overload_set_type` and `cpp_overload_set_value`, instead of having an arbitrary name. Examples that demonstrate the old name is arbitrary can easily be seen in tests like `cpp_namespace.carbon` and `decayed_param.carbon`, but careful review would show that all old names are arbitrary, though often luckily almost make sense. We might want to have a proper name for these, but it's beyond the scope of this crash fixing change. See #6156. Part of #5915.
