Unlike all other Skottie effects, motion blur requires sampling at multiple
points on the timeline.
To support this:
1) Introduce MotionBlurEffect - a custom SG render node which can drive
the timeline of its subtree using an sksg::Animator.
2) Introduce MotionBlurController to swap for a regular LayerController
when needed. MotionBlurController dispatches time ticks to
MotionBlurEffect instead of directly to the layer animators.
The actual motion blur impl is based on
https://skia-review.googlesource.com/c/skia/+/221416.
Motion blur requires Lottie files exported with this BodyMovin patch:

Implement radial wipe with a sweep gradient shader mask filter.
The implementation is slightly convoluted because edge feathering requires a real blur, which in turn requires content layer isolation.
So there are two distinct operation modes:
- no feather -> draw the content directly into the dest buffer, with the mask filter
deferred in SG context
- feather -> draw the content into a separate layer, then blend (dstOut) the composed
blur+shader mask on top

Each animator can have multiple range selectors, whose combined "coverage"
modulates how the animator props compose with other/initial props.
Since there can be multiple animators with different/arbitrary selectors,
we compute independent property values for each fragment.
Supported features:
- start, end, offset, amount
- units: percentage, index
- based-on: characters-only for now
- mode: add-only for now
- shape: square-only for now

Introduce a PropertyObserver to receive property notifications for layer
and shape nodes.
Properties are communicated using strongly-typed "handles", which act
as impedance adapters between the AE/BM model and the internal Skottie
model.

This is in preparation of keyframed text, which will require access to
