Reduce switch split flicker on protrait split
Due to insets for tasks would be changed when switch split on protrait mode, it lead to some flicker. Attach screenshots before switch and fading out after switch animation finished to reduce flicker. Also update animation algorithm to reduce flicker occured when top to bottom case. Fix: 240517067 Test: manual Test: pass existing tests Change-Id: I66991b40b2ab8f410abcb800e9ca6e80222faa8c
