<pre>Implement prefers-reduced-motion media query
https://bugs.webkit.org/show_bug.cgi?id=163250
<rdar://problem/28704129>
Reviewed by Simon Fraser.
Source/WebCore:
Implement the prefers-reduced-motion media query, as
described in https://github.com/w3c/csswg-drafts/issues/442.
Tests: fast/media/mq-prefers-reduced-motion-forced-value.html
fast/media/mq-prefers-reduced-motion.html
* Configurations/WebCoreTestSupport.xcconfig: Link against AppKit and UIKit.
* css/CSSValueKeywords.in: New keyword for "reduce".
* css/MediaFeatureNames.h: Add prefers-reduced-motion.
* css/MediaQueryEvaluator.cpp:
(WebCore::prefersReducedMotionEvaluate):
* css/MediaQueryExp.cpp:
(WebCore::featureWithValidIdent):
(WebCore::isFeatureValidWithoutValue):
* platform/Theme.h: New API to detect the system accessibility settings.
(WebCore::Theme::userPrefersReducedMotion):
* platform/ios/ThemeIOS.h:
* platform/ios/ThemeIOS.mm:
(WebCore::ThemeIOS::userPrefersReducedMotion):
* platform/mac/ThemeMac.h:
* platform/mac/ThemeMac.mm:
(WebCore::ThemeMac::userPrefersReducedMotion):
* testing/Internals.cpp: Expose the same API to internals, so that
a test can examine the value too.
(WebCore::Internals::userPrefersReducedMotion):
* testing/Internals.h:
* testing/Internals.idl:
* testing/Internals.mm:
(WebCore::Internals::userPrefersReducedMotion):
* page/Settings.h: New setting to override the system value...
* page/Settings.in:
* testing/InternalSettings.cpp: ... plumbed through internals.

One test checks the system value. The other test overrides
the system values to make sure as much as possible is working.
