Add support for subgrids and fix some other grid properties
This covers the `subgrid <line-name-lists>?` for `grid-template` (for gecko, and hence, stylo).

Enable 'fill-opacity' and 'stroke-opacity' for '-moz-context-properties' to make the context-{fill|stroke}-opacity work in SVG-as-an-image.

This will allow us to fix propagation of text-decoration, and also to implement
inlinization of ruby kids.

Before this change, the `ComputedStyle` struct that is part of permanent style
data per element holds 2 `StrongRuleNode`s (unvisited and visited) and 2
`Arc<ComputedValues>` (unvisited and visited).
Both rule nodes and the visited values don't actually need to be here. This
patch moves these 3 to new temporary storage in `CascadeInputs` on
`CurrentElementInfo` during the match and cascade process. Rule nodes are
pushed down inside the `ComputedValues` for later access after the cascade.
(Visited values were already available there.)
The permanent style data per element now has just the `Arc<ComputedValues>` for
itself and eager pseudo-elements (plus the `RestyleHint`).

Right now when calling getComputedStyle with an element from another document,
we return the style using the pres context of that document, not of the document
of the window getComputedStyle was called on, so this holds.
But it will stop holding if we ever change this, so assert it doesn't happen.

stylo: Make -moz-{tab-size, box-flex, image-region, outline-radius} animatable.
Make -moz-tab-size, -moz-box-flex, -moz-image-region, and -moz-outline-radius animatable, so test_transitions_per_property.html doesn't get any exception of these properties.

Let's follow how Gecko does for this part (in nsRuleNode::ComputeListData).
We set mImageRegion.height or mImageRegion.width to zero if bottom or right is
None (i.e. auto).
