Derive ToComputedValue

Browse source 
For now, only impls for types like in style::values::generics can be derived.

This also needed a few ToComputedValueAsSpecified impls that I would like to
replace by some #[to_computed_value(clone)] attribute, but I think it is ok
to keep it like this for now.
