Reviewed by Chris Dumez.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Partial Merge - https://chromium.googlesource.com/chromium/src.git/+/30ecdaf63da0c5e1d81caf93c9836ec5564d9647

This fixes a couple of bugs with the CSSPreloadScanner that made it miss
rules in which the URL wasn't quoted or the rule didn't end with a
semicolon etc.

* Source/WebCore/html/parser/CSSPreloadScanner.cpp:
(parseCSSStringOrURL): Add comments and also add "if" clause for 'single' and
'double' clauses and do other clean-ups
* LayoutTests/imported/w3c/web-platform-tests/loading/preloader-css-import-no-quote.tentative.html: Add Test Case
* LayoutTests/imported/w3c/web-platform-tests/loading/preloader-css-import-no-quote.tentative-expected.txt: Add Test Case Expectation
* LayoutTests/imported/w3c/web-platform-tests/loading/resources/dummy.css: Add Test Resource
* LayoutTests/platform/glib/imported/w3c/web-platform-tests/loading/preloader-css-import-no-quote.tentative-expected.txt: Add Platform Specific Expectation
