Create a constellation_traits crate (#36088)

Browse source 
This change creates a `constellation_traits` crate. Previously messages
to the `Constellation` were in the `compositing_traits` crate, which
came about organically. This change moves these to a new crate which
also contains data types that are used in both compositing/libservo and
script (ie types that cross the process boundary). The idea is similar
to `embedding_traits`, but this is meant for types not exposed to the
API.

This change allows deduplicating `UntrustedNodeAddress`, which
previously had two versions to avoid circular dependencies.

//! Types used by the embedding layer and/or exposed to the API. This crate is responsible for
//! defining types that cross the process boundary from the embedding/rendering layer all the way
//! to script, thus it should have very minimal dependencies on other parts of Servo. If a type
//! is not exposed in the API or doesn't involve messages sent to the embedding/libservo layer, it
//! is probably a better fit for the `constellation_traits` crate.
