LibWeb: Calculate y of a box before resolving width in BFC

Browse Source 
Calculating width of a box in BFC requires having resolved y to be able
to check if a box overlaps with any floating boxes.

This change makes compute_width() to be called after finding y
position. That also required to move resolving of vertical metrics
in the beginning of a box layout process to have vertical margins
resolved before finding y position.
