WindowSerer+LibGUI: Send multiple rects in invalidation/flush messages.
This patch moves to sending up to 32 rects at a time when coordinating the painting between WindowServer and its clients. Rects are also merged into a minimal DisjointRectSet on the server side before painting. Interactive resize looks a lot better after this change, since we can usually do all the repainting needed in one go.
