Sam Atkins c57975c9fd LibWeb: Move and rename CSSStyleValue to StyleValues/StyleValue.{h,cpp}
This reverts 0e3487b9ab.

Back when I made that change, I thought we could make our StyleValue
classes match the typed-om definitions directly. However, they have
different requirements. Typed-om types need to be mutable and GCed,
whereas StyleValues are immutable and ideally wouldn't require a JS VM.

While I was already making such a cataclysmic change, I've moved it into
the StyleValues directory, because it *not* being there has bothered me
for a long time. 😅
