This is on top of https://github.com/servo/servo/pull/15928.
Now that cascade() gets a Device ref, we can use the default computed values
from there to avoid propagating that state all over the place.

cc @bholley, didn't end up renaming the `layout_parent` thing, because it made the cascade way more verbose (and difficult to understand IMO) unnecessarily, and you said you were ok-ish with it.

<!-- Please describe your changes on the following line: -->
I began this for making the `CalcLengthOrPercentage` represent `LengthOrPercentage` (instead of the enum we already have), but only later did I realize that it will make `LengthOrPercentageOrFoo` types fatty (which is the problem we're trying to avoid - #15061) and so, I dropped that attempt. Along the way, I introduced an internal type for `Length`, for representing all its non-calc variants (which are `Copy`). We could still have this type for the `LengthOrPercentageOrFoo` types which don't really need `Length` since they already have their own variants for calc.
r? @Manishearth @emilio @SimonSapin or anyone interested
