Automatic update from web-platform-tests [LayoutNG] Add the "simplified" layout pass. This introduces the simplified layout algorithm. This is triggered when - An OOF descendant has its constraints changed. - The block-size of a fragment changes in size. There are several nuanced details with this algorithm. E.g. determining the correct static position for an OOF descendant.
