In a later patch, we'll want to queue up some tasks to run when the
Servo traversal is one, and the ServoStyleSet seems like the natural
place to store those tasks. We could probably find the ServoStyleSet
by chasing a bunch of pointers from the task-adding call sites, but
it seems simpler just to make it available directly.

Text style is always resolved via ServoStyleSet::ResolveStyleForText, either
from the frame constructor initially, or from
ServoRestyleManager::ProcessPostTraversalForText.
So text-only adjustments should go there instead. Since that doesn't call into
cascade(), all the code that passes `pseudo` there is dead code we can remove.

This also moves the NoteStyleSheetsChanged to RecordStylesheetChange, which
makes more sense, and stopped special-casing author styles, since it's not
needed now.

We will use this type later in this patch series in nsSMILCSSProperty so this
patch moves it to a separate file so it can be re-used.

Also this patch add nsIAtom as an argument to ResolveTransientStyle() to call
the new function ResolveServoTransientStyle easier. The only call site of the
ResolveTransientStyle() has already nsIAtom* there.

This argument will be used to control whether we are restyling in preparation
for reframing a subtree, which can avoid generating any change hints, as we
aren't preserving the frames that they would otherwise apply to.

This patch exists to avoid a crash in layout/style/test/test_animations.html. We end up
generating some ::before content, which causes us to style the new subtree at [1]. In
StyleNewSubtree, we fail the !postTraversalRequired assertion because
PrepareAndTraverseSubtree decided to traverse the tree twice (once to style it, and again
to restyle it for animations), and return that a post-traversal is needed.
The reason this issue happens with my NAC patches and not without is that we were previously
filtering out generated ::before content from the servo traversal, so the servo traversal
wouldn't have reached it and (presumably) the animation restyle wouldn't have happened and
we wouldn't have returned true for needing a post-traversal.

While we're here, don't re-recompute the default computed values, just grab them
from the device.

We create the SequentialTask only if:
* We have no old computed values and we have animation name style in the new
computed values.
* Any animation properties is changed.
* display property is changed from 'none' and we have animation name style.
* display property is changed to 'none'.
In a subsequent patch we skip the SequentialTask if we have no running
animations and the display propery is changed to 'none'.

The restyle request during restyling is a result of creating/updating/removing
CSS animations that will come from a SequentialTask which will be implemented
in a subsequent patch.
