[BlinkGenPropertyTrees] SVG animations should not reset layer invalidations

When an SVG image has animations, SVGImage::ServiceAnimations is called
which updates animations via DocumentAnimations::UpdateAnimations. For
blink generated property trees (BGPT), this is done during paint (see:
LocalFrameView::RunPaintLifecyclePhase) and, because paint is skipped
when updating svg image animations, it must be explicitly invoked for
svg animations. (For non-BGPT, this is done as part of the compositing
step which precedes paint). Updating animations may invalidate the SVG
image's paint layers.

Before this patch, the paint layer invalidations were cleared which
caused the later svg image paint to incorrectly use stale paint data.
