Callum Law e6ddb7db9e LibWeb: Store EdgeStyleValue sub-values directly
As well as being required to implement absolutization this also means we
now bypass a limitation with `LengthPercentage` where we would always
use `SerializationMode::Normal` for the constituent lengths which gains
us some WPT passes
