Fix stale transform values in view transition snapshots
https://bugs.webkit.org/show_bug.cgi?id=310181
Reviewed by Matt Woodrow.
When snapshotting with flattened compositing layers,
`RenderLayer::renderableTransform()` can use `m_transform`, which may not
reflect the current value of an accelerated transform-related animation.
When `PaintBehavior::Snapshotting` is set and a transform-related accelerated
animation is running, use `animatedStyle()` to compute the renderable transform
instead of `m_transform`. This mirrors the existing `currentTransform()`
handling for accelerated transform animations and keeps snapshot rendering
aligned with the current animated value.
* Source/WebCore/rendering/RenderLayer.cpp:
(`WebCore::RenderLayer::renderableTransform`):
Use `animatedStyle()` during snapshotting for running accelerated
transform-related animations.
