Andreas Kling 66618a666b LibWeb: Implement CSSStyleDeclaration.{set,remove}Property close to spec
We already had setProperty() but it was full of ad-hoc idiosyncracies.
This patch aligns setProperty() with the CSSOM spec and also implements
removeProperty() since that's actually needed by setProperty() now.

Some things fixed by this:
- We now support the "priority" parameter to setProperty()
- Element "style" attributes now update to reflect CSSOM mutations
