Placed worklets implementation behind a pref
<!-- Please describe your changes on the following line: -->
At the moment, worklets are always exposed, even though their spec is still a draft. This PR hides them behind a pref.

Also includes an incidental bugfix for the rendering order of text decorations.
This change depends on servo/webrender#1454 being merged and upstreamed to servo.
In animation-only restyle, we just need to check the element
has animation restyle hints or has recascade self which is a result
of animation-only restyle for ancestors.
has_current_styles() in Servo_ResolveStyle() is intentionally left there,
it will be changed in a subsequent patch.

This patch also removes the duplication of style contexts during the
restyle, because otherwise pointer equality of ServoComputedValues stops
holding (and we assert on that in a few places)
