  [threaded-animation-resolution] add support for CSS Motion Path properties
https://bugs.webkit.org/show_bug.cgi?id=269503

Reviewed by Dean Jackson.

With threaded animation resolution we can now add support for accelerated interpolation
of CSS Motion Path properties, the `offset` shorthand and its longhands.

To do this, we need to add two new members to `AcceleratedEffectValues`:

    std::optional<TransformOperationData> transformOperationData;
    TransformBox transformBox;

These two new members are required to be able to call into an alternate version of the
`MotionPath::applyMotionPathTransform()` method which works without a RenderStyle, but
rather using individual properties read from RenderStyle. We also adjust the `AcceleratedEffectValues`
constructor to take in a renderer to be able to set up those two new members.

This also required a small refactor related to `BlendingContext` since we need to be
able to adjust the context for discrete interpolation in the case of the `offset-rotate`
property which has an ASSERT() to check we only call its blending function for a discrete
interpolation if the context reflects that.
