Auto generate MediaFeatureNames, its macros and MediaTypeNames

As part of the review of https://codereview.chromium.org/171383002/
it was requested that the required static strings for the media features and types will be generated as part of the build system.
This CL implements that request.

Move all RefPtr's to CSSValue to oilpan transition types, except for the one in CSSCursorImageValue.

This change gets rid of all but one RefPtr to CSSValue. I have introduced a few persistents core/animation/..., core/css/StylePropertySet, and ElementStyleResources. I plan to attack the one in CSSCursorImageValue subsequently, and then change CSSValue from RefCountedGarbageCollected to GarbageCollectedFinalized.
