  [SVG] Enable approximate repaint bounding box computation

Reviewed by Cameron McCormack.

This is one step of the patch series implementing approximate repainting rect for SVG path, derived from blink's work[1].

This patch flips approximate repaint bounding box computation. This also reveals that some accessibility thing is relying
on repaint bounding box while it should not, but for now this patch is keeping it.
This offers 0.53% progression in Speedometer3.0: in subtests, React-Stockcharts-SVG 4.78% progression and Charts-observable-plot 1.37% progression.
