Through the /css/css-text/white-space/control-chars-* tests, this accounts for about 60 towards the browser-specific-failures for Safari on https://wpt.fyi (i.e., 1.5% of current failures).

Marking as r?. EWS will show some red, but that's just because this patch depends on https://bugs.webkit.org/show_bug.cgi?id=215643 which hasn't been landed yet.

This patch modifies the imported WPT tests. Please ensure that any changes on the tests (not coming from a WPT import) are exported to WPT. Please see https://trac.webkit.org/wiki/WPTExportProcess
