libservo: Re-export types that are used by servoshell (#39586)

servoshell should not depend on internal Servo crates. Instead,
`libervo` should re-export any types that are used by embedders. This
change does that re-export for private types currently used by
servoshell.

Testing: This just changes the way types are imported, so curent tests
should suffice.
