style: Cleanup and fix interpolation of SVG lengths.

Browse source 
Instead of storing them as LengthPercentage | Number, always store as
LengthPercentage, and use the unitless length quirk to parse numbers instead.

Further cleanups to use the rust representation can happen as a followup, which
will also get rid of the boolean argument (since we can poke at the rust length
itself). That's why I didn't bother to convert it to an enum class yet.
