Hoist layout update out of SVGGraphicsElement::GetBBox and overrides
Call Document::UpdateStyleAndLayoutIgnorePendingStylesheets() in the DOM
entrypoint instead of in each GetBBox implementation/override. Add
DCHECKs as needed in the GetBBox implementations instead to assert the
precondition.
Adjust ResizeObservation::ComputeTargetSize (which shouldn't need to
update the layout anyway) to account for this.
