  [SVG] Consult white-space-collapse instead of white-space to determine preserving white-space
https://bugs.webkit.org/show_bug.cgi?id=258426

Reviewed by Simon Fraser.

Now that the white-space-collapse longhand exists, it should be used for consulting white-space preservation, text-wrap is not taken in
account given SVG white space processing (applySVGWhitespaceRules) is unrelated to wrapping.

As a result, white-space: pre-wrap & white-space: preserve balance/pretty/stable will now behave like white-space: pre; for SVG white space
processing.
