Parse animation-name in CSSPropertyParser with CSSParserTokens

Parse animation-name in CSSPropertyParser with CSSParserTokens

This patch moves the parsing logic for animation-name out of the
LegacyCSSProperty and into the CSSPropertyParser. This property has
special behaviour when specified as -webkit-animation-name, so
parseSingleValue is updated to take an unresolved properties instead
of a resolved property. consumeAnimationValue's arguments are extended
so we can continue counting usage of the non-standard behaviour.

lgtm with one nit.

File third_party/WebKit/Source/core/css/parser/CSSPropertyParser.cpp (right):

https://codereview.chromium.org/1410223004/diff/1/third_party/WebKit/Source/c...
third_party/WebKit/Source/core/css/parser/CSSPropertyParser.cpp:946: // Legacy
support for strings in prefixed animations
Officially this requires a period at the end :)
