Reviewed by Tim Nguyen.

This patch is to align WebKit with Gecko / Firefox and Blink / Chromium.

Merge - https://chromium.googlesource.com/chromium/blink/+/972c6ca7b5ffa48a099b53cfc720a0aef3bf850e

This patch removes special casing of zooming of SVG when computing
border-width, where border-widths value does not scale with zoom level
for SVG elements. It was quirk which was removed from Blink in 2014 to
match with Firefox since it was not supported by any web-specification.
