To support visited styles, we match and cascade a separate set of styles any
time we notice that an element has a relevant link.
The visited rules and values are held in `ComputedStyle` alongside the
regular rules and values, which simplifies supporting various APIs like
`cascade_primary_and_pseudos` which expect easy access to previously matched
rules.
To simplify passing the additional values around, an additional reference to the
visited `ComputedValues` is placed inside the regular `ComputedValues`.

Adjust the matching process to look for a "relevant link" while matching. A
"relevant link" is the element being matched if it is a link or the nearest
ancestor link.
Matching for links now depends on the `VisitedHandlingMode`, which determines
whether all links match as if they are unvisited (the default) or if the
relevant link matches as visited (and all others remain unvisited).
If a relevant link is ever found for any selector, track this as part of the
`MatchingContext` object. This is used in the next patch to determine if an
additional match and cascade should be performed to compute the styles when
visited.

[script/textinput] Fix warning: unreachable pattern
The `cfg` attribute in use resulted in two match arms for two cases on
`macos`. Since both arms had a main functionality in common, I merged
them and conditions the extra `macos` part.

Fix the -Z wr-no-batch option.
The DebugOpts struct uses the Default trait to set all the values
to false initialily. So bools in the DebugOpts struct must be
negative verbs to work correctly.
This drops the draw call count on HN from ~2000 back to ~5.

We only use whether the return value is IMPORTANT_RULES_CHANGED or not, so we
can just return true if an important rules was changed in the function.
Also, we can just return false in case of animation rules changes sine for
animation we can ensure there is no importan rules.
Because of these changes, replace_rule_node does not borrow |result| so that
we can drop a scope there.

In the case where we process an element which has SMIL animations in normal travesal
the SMIL styles must have been computed in animation-only restyles. So we
have only to pick the computed styles instead of recomputing it.
Although there are no specific tests for this yet if any code does try
to perform addition or accumulation with a font-stretch value it will
likely fail the bounds check in the Into trait. To avoid that this
patch provides an basic implementation of add_weighted for font-stretch
that should work correctly with portions whose sum is outside the [0.0,
1.0] range.
Fix stylo's text-overflow handling to match gecko.
A single value sets the text-overflow on the _end_ of the text, not both start and end.
