[last-baseline] Set multicol last-baseline to lowest of all fragments
See: w3c/csswg-drafts#7639 Effectively we need to propagate the last baseline from the lowest of all fragments. This does change the baseline of a multi-col within a inline-block context. Bug: 885175 Change-Id: I8385f89cbe0bb3cc89fc972546f56ddd9ae391bd
