Reviewed by Antti Koivisto.
This patch aligns WebKit with Gecko / Firefox and Blink / Chromium. Also,
it fixes it for both Legacy SVG and Layer Based SVG engine.

SVG intrinsic dimensions need to be transposed for vertical writing modes
to correctly map physical dimensions to logical layout coordinates.
This patch updates computeIntrinsicSize() to transpose dimensions for
vertical writing modes, and updates preferredAspectRatio() to handle both
intrinsic size and viewBox ratios correctly in vertical contexts.
