Changes saveAppPair to take a general number of apps, rather than just 2. At the moment, this will not change anything, since GroupedTaskViews are still hard coded to contain 2 apps. Bug: 349828130 Flag: com.android.wm.shell.enable_flexible_split Test: No effect on behavior, just a small refactor. Change-Id: I6f86210ab4662f0d3a8fba1f6bb6fd78391e7fa2
