Now that we are standardizing on the `_traits` crates becoming `_api` and exposing the API of the crate that they get their name from [^1], `script_layout_interface` becomes `layout_api` as it exposes the API for `layout` that is used by `script` This brings the crate in line with the naming of the other ones in `shared`. [^1]: https://servo.zulipchat.com/#narrow/channel/263398-general/topic/Organizing.20*_traits.20crates/with/396893711 Testing: This should not change any behavior and thus is covered by existing tests.
