This should make it somewhat easier to experiment with alternative representations in the future. To reduce churn, this commit leaves the String field public, though. Also, this will allow us to use the default String type to represent the IDL USVString type, which explicitly forbids unpaired surrogates, ans as such is a better match to the Rust String type.
