LibWeb: Return Optional from StyleProperties::box_sizing()

Browse source 
This function was written as if it returned `Optional<CSS::BoxSizing>`
but actually returned a plain `CSS::BoxSizing`, meaning if the property
was not set or was invalid, it would return whichever enum value was
first. This wasn't visible because we don't yet pay any attention to
the `box-sizing` property.
