LibWeb: Handle numeric font-weights

Browse source 
The code was assuming the font-weight would be a Length, apparently
since NumericStyleValue didn't exist at the time. Now, it's always a
numeric value, so treat it as such.

We also replace the hardcoded numbers with references to the FontWeight
enum.

Also, it was always setting the weight to 900, so that has been fixed.
