Remove the retrieval cache on system_server. It's not needed at this point. Instead, we cache the low-res thumbnails on SystemUI side that will be visible when recents launches. For that, we introduce a strong thumbnail cache, which gets filled up whenever the task stack changes. Also fix a couple of issues like that the visibility report was pretty wrong as well as some tasks got unloaded because tasks were bound before layout happend. Also fix a merge issue where we didn't load the reduced resolution thumbnail :/ Test: TaskSnapshotCacheTest Test: Open a couple of apps, open recents, make sure all thumbnails are already loaded.
