Fix a crash caused by a bug introduced in C++ overloads support in GetScopeIdOffset() (#6151)

Browse Source 
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.
