LibWeb: Boxes that establish FFC or GFC should avoid overlapping floats

Browse source 
Before, we only ensured that boxes establishing BFC did not overlap
with floats because that is what CSS 2.2 specification says. However,
we should also apply the same for boxes establishing FFC or GFC as this
aligns with the behavior of other browsers.

Fixes https://github.com/SerenityOS/serenity/issues/21095
