This lifts a bunch of string conversions higher up the stack, but allows us to make the servo code use utf-8 unconditionally, and seemed faster in my benchmarking (see comment 0). It should also make a bunch of attribute setters faster too (like setting .cssText), now that we use UTF8String for them (we couldn't because we couldn't specify different string types for the getter and setters).
