LibWeb: Avoid leaking infinite remaining_free_space in FFC calculation
After switching to fixed-point arithmetic in CSSPixels, it no longer supports representing infinite values, which was previously the case for remaining_free_space in FFC. Using Optional that is not empty only when value is finite to store remaining_free_space ensures that infinity is avoided in layout calculations.
