layers: Add component awareness to SC interface matching
- Adds more tests for mismatch by component and by location
- Removes dead handling of builtins (we only care about collecting builtin /decorations/ to aid in the interface block handling;
we don't really care about producing the set of builtins used overall.)
Some SC error messages change slightly, as interstage locations now include the component index.
Fixes internal bug 26609754
