LibWeb: Allow calc() values in image sizes attribute

Browse source 
Note that we currently can't resolve calc() values without a layout
node, so when normalizing an image's source set, we'll flush any pending
layout updates and hope that gives us an up-to-date layout node.

I've left a FIXME about implementing this in a more elegant and less
layout-thrashy way, as that will require more architectural work.
