This patch looks bigger than it is, but it's mostly because of plumbing. To implement revert-layer we need not only the cascade origin of the declaration, but the whole cascade level, plus also the layer order. In order to do this, encapsulate these two things inside a 32-bit `CascadePriority` struct and plumb it through the rule tree and so on. This allows us to remove the packing and unpacking of CascadeLevel, though I kept the ShadowCascadeOrder limit for now in case we need to reintroduce it. Fix `!important` behavior of layers while at it (implementing it in `CascadeLevel::cmp`, spec quote included since it was tricky to find) since some revert-layer tests were depending on it. The style attribute test is failing now, but follow-up commit fixes it, see spec issue. In terms of the actual keyword implementation, it's sort of straight-forward: We implement revert and revert-layer in a shared way, by storing the cascade priority that reverted it.
