Rename script_layout_interface to layout_api (#37591)

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`.

Testing: This should not change any behavior and thus is covered by
existing tests.
