compositor: Unify the cross process and in-process API (#36443)

Browse source 
Because there used to be two traits exposing messages to the compositor,
there were two kinds of messages that could be sent:

1. In-process messages from the `Constellation`
2. Cross-process messages from other parts of Servo

Now these two types of messages can be unified into one type. With that
done the compositor can simply keep a single `IpcReceiver` for all
messages, instead of having to set up a route for the cross-process
messsages. This decreases overhead of cross proceses messages a bit, but
more importantly solves an issue where Servo would rely on the
compositor's cross-process message route after the `Constellation` had
called `ROUTER.shutdown()`.

This is part of #36442.

Testing: This is covered by existing WPT tests.
