Richard Smith 4a10d29b99 Include the complete type witness for a class in its SemIR output. (#4599) 
This seems slightly redundant for a locally-defined class, where there
will be a complete_type_witness instruction earlier in the class, but is
important for imported classes, where we're currently doing the wrong
thing in a way that's invisible in formatted SemIR.
