A couple of minor functional changes here: - We now always create a `name_ref` for the name referred to by the right-hand operand of member access. Previously we skipped creating this instruction if the referenced name was a field, and just created the field access instruction. This makes our processing of member accesses and our SemIR representation a bit more uniform. - We now perform lookup into the type of the left-hand operand if it's any type with a scope, not just for classes. This means we do lookup into interface types. However, doing so isn't really useful yet because it always finds an associated entity that isn't usable by itself. This changes the diagnostic in `toolchain/check/testdata/interface/fail_todo_facet_lookup.carbon`.
