Refactor Gradient

Browse source 
In a similar way to Position, now specified and computed gradients share
a common Gradient type defined in style::values::generics::image.

This allows us to reuse most code for many style traits like ToCss,
HasViewportPercentage and ToComputedValue.

The test changes are the fallout of the disappearance of AngleOrCorner::None,
which align our code to the spec for serialisation, where components that can
be omitted should be omitted.
