0f54d797d2 LibWeb: Handle pre-existing animations when considering animation-name 
If a DOM::Element has an animation-name property, then in addition to
remembering where it came from, it will also remember the
Animations::Animation object that was created for it. This allows
StyleComputer to cancel that animation if the animation-name property
changes as well as to apply any changes required (for example, if
animation-play-state changes from "running" to "paused", it needs to
call .pause() on the animation).

ae3326a447 LibWeb: Transition StyleComputer to Web Animations 
With this commit, we are finally running animations off of the web
animations spec! A lot of the work StyleComputer is doing is now done
elsewhere. For example, fill-forward animations are handled by
Animation::is_relevant() returning true in the after phase, meaning the
"active_state_if_fill_forward" map is no longer needed.

06a8674eec LibWeb: Simplify Animation::update_finished_state a bit 
This removes the two boolean hack in favor of using the existing
mechanism to remove queued tasks. It also exposes the element
invalidation behavior for call sites that don't necessarily want to
update the finished state, but still need to invalidate the associated
target.

88518c29ca LibWeb: Combine "pending" and "ASAP" animation task states 
It seems that the difference between pending and ASAP in the spec is
only to allow the implementation to perform implementation-defined
operations between the two states. We don't need to distinguish the two
states, so lets just combine them for now.

7d69fa0ccf LibWeb: Partially implement the "process a keyframes argument" procedure 
Keyframes can be given in two separate forms:

- As an array of separate keyframe objects, where the keys of each
  keyframe represent CSS properties, and their values represents the
  values that those CSS properties should take

  e.x.:
  [{ color: 'red', offset: 0.3 }, { color: 'blue', offset: 0.7 }]

- As a single monolithic keyframe object, where the keys of each
  keyframe represent CSS properties, and their values are arrays of
  values, where each index k represents the value of the given
  property at the k'th frame.

  e.x.:
  { color: ['red', 'blue'], offset: [0.3, 0.7] }

This commit only implements the first option, as it is much simpler. See
the next commit for the implementation of the second option.
