Prepare height calculation methods in LayoutFlowThread for nested multicol.
Rename pageLogicalHeight() in LayoutMultiColumnSet to
pageLogicalHeightForOffset(), so that it matches the naming of
pageRemainingLogicalHeightForOffset().
Move the innards to LayoutMultiColumnSet. And some 0 -> LayoutUnit() cleanup.
Had to adjust some call sites because of this and introduce
isPageLogicalHeightKnown().
No behavioral changes intended for now.
