The orphan rule is defined here: https://docs.carbon-lang.dev/docs/design/generics/details.html#orphan-rule **Orphan rule:** Some name from the type structure of an `impl` declaration must be defined in the same library as the `impl`, that is some name must be *local*. Update tests that were running afoul of the orphan rule unintentionally. Add tests that do violate the rule intentionally and test edge cases.
