Currently, Servo uses ComputeSquaredDistance derive for
SvgLengthOrPercentageOrNumber, so servo can't calculate between
LengthOrPercentage and Number.
This PR will allow calculating these value.

We need to use enum instead of Either since we can't interpolate stroke-* between
unitless length and unit length(e.g. '5' -> '10px').
This coomit make following:
* Introduce SVGLengthOrPercentageOrNumber on computed and specified values.
* Make SVGLengthOrPercentageOrNumber animatable.
* Make stroke-dasharray not-accumulate.
Introduce ComputedUrl
<!-- Please describe your changes on the following line: -->
Use the new `ComputedUrl` type for computed types and `SpecifiedUrl` for specified types instead of using the `SpecifiedUrl` implementation for both.

As silly as it may seem to specify font-sizes using viewport units, we weren't
handling zoom for them correctly either.

stylo: Bug 1374233 - Clamp interpolated values for properties which need to be restricted
Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.
