LibWeb: Only remember source CSSStyleDeclaration for animation-name

Browse source 
We were saving to source declarations for *every* property, even though
we only ever looked it up for animation-name.

This patch gets rid of the per-property source pointer and we now keep
a single pointer to the animation-name source only.

This shrinks StyleProperties from 6512 bytes to 4368 bytes per instance.
