Limit visited cascade for reparenting
The specialized cascade flow in `stylist::compute_style_with_inputs` (used with
reparenting) currently computes all properties for visited styles, but we only
need visited-dependent properties.
This adds the cascade flag to reduce the work to visited-dependent properties
only, like we do for the regular cascade flow.

There are two key steps when resolving text styles with `::first-line`:
1. `ResolveStyleForText` computes the initial style of the text via
`Servo_ComputedValues_Inherit`
2. `ReparentStyleContext` is called to update style data when the first line
of text is moved to be a child of the `::first-line` frame
Before this patch, `Servo_ComputedValues_Inherit` would clear out unvisited
rules, but visited styles (with rules inside) were cloned as-is, meaning that
step 1 might leave the text node with a style that has:
* Unvisited rules: None
* Visited rules: Some
When we later go to step 2 and re-parent onto the `::first-line` styles, we try
to cascade with these leftover visited rules. This causes any `::first-line`
styles from our parent to be overridden by these rules which are no longer quite
right for the new frame tree.
In this patch, we resolve this by changing `StyleBuilder::for_inheritance`
(which is used by step 1's `Servo_ComputedValues_Inherit`) to also clear out
visited rules, so that we use the same logic for both unvisited and visited text
styles when reparenting onto the `::first-line` frame.

style: Support more selectors in the style sheet invalidator.
In addition to being able to invalidate just based on local name, this
also adds support for invalidating based on selectors with no ancestor
combinator in them (resulting in a RESTYLE_SELF for those elements that
match).
