Update MotionTileEffect to avoid rebuilding shaders redundantly,
at render time:
1) build all shaders at revalidation time
2) cache the layer content picture separately, and only rebuild when
the layer content changes
To support #2, add some SG helpers for querying subtree inval state.
With this change, we avoid all render time allocations.

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:

Most layer animators are scoped at the LayerController level - except for
animators related to layer transforms.
The reason for this exception is that dependent/child layers require up-to-date
transform chains even when the parent layer is inactive.
Currently, to escape LayerController scoping, layer transform animators
are stored directly in the parent (composition) scope. This works fine
for the initial purpose, but discards layer->transform-animator ownership
info.
Upcoming features (motion blur) require knowledge of all animators associated
with a given layer, and the current scheme gets in the way.
To address this problem, update the layer controller logic to
1) store all layer animators (including transform-related) in the controller
scope
2) always dispatch ticks to transform-related animators
No functional changes are expected.

We used to rely solely on visual bounds for vertical alignment. That
had the downside of leading/trailing empty lines being ignored.
Then https://skia-review.googlesource.com/c/skia/+/220916 switched to
using typographical bounds. This approach produces results in line
with AE, but allows some glyphs to overflow the alignment boundary.
This CL introduces a hybrid approach:
1) for standard AE text alignment, continue to use typographical bounds
2) for Skottie VAlign extensions (sk_vj), use the union of typographical
and visual bounds - this should mitigate both issues mentioned above

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

The current implementation applies constant coverage (outside selector

But the integral range is clamped to the valid index domain and its
extremes are always assumed to have partial coverage - so we never get
to constant-blit the full buffer when the interval is outside, which
can yield incorrect coverage for the first/last fragments.
