Remove zoom special casing of SVG when computing border-widths

Remove zoom special casing of SVG when computing border-widths

Ever since border-image-width was implemented in

https://bugs.webkit.org/show_bug.cgi?id=67657

border-widths values haven't been scaled with the zoom level for SVG
elements. Remove the special casing since it doesn't seems to be any
good reason for having it. Firefox doesn't do anything of the sort and
there is no specification support for it.

Found this one when trying to understand how useSVGZoomRules() works (and if we
can remove it).

Unsure who is suitable to review this but I see that dglazkov has been poking at
useSVGZoomRules before. Take a look when you have a cycle.

Looping in some more reviewers that might have opinions here.

Also, see https://codereview.chromium.org/300553009 where I experiment with
removing more of useSVGZoomRules(). Not done with that yet though.

I'm not especially knowledgeable about how border-image works, but this patch
looks right to me (and matches Gecko).

LGTM
