LibWeb: Fix infinite recursion when grid has "max-width: max-content"

Browse source 
With this change "max-width: max-content" is treated as "none" when
the available width is also "max-content". This fix prevents a stack
overflow in the grid track size maximization algorithm by avoiding
recursive calls to calculate_max_width() when determining the maximum
grid container size.
