Source/WebCore:

Implemented the ::cue() pseudo-element with an argument that may hold a simple selector list.
This enables matching cue objects by the class name.

Test: media/track/track-css-matching.html

* css/CSSGrammar.y.in: support parsing the ::cue() with an argument.
* css/CSSParser.cpp:
(WebCore::CSSParser::detectFunctionTypeToken): tokenize the 'cue'.
(WebCore::CSSParser::updateSpecifiersWithElementName): do not set the tag for the cue pseudo-element because
the ::cue may match elements with different tags.
(WebCore::CSSParser::updateSpecifiers): the behavior for the PseudoCue selector should be same as for
unknown pseudo elements - the pseudo-element should stay on top of the selector chain.
* css/CSSSelector.cpp: added the type detection for the new selector.
(WebCore::CSSSelector::pseudoId):
(WebCore::nameToPseudoTypeMap):
(WebCore::CSSSelector::extractPseudoType):
