Add logs for NotificationStackScrollLayout traversal removal of transient group child ExpandableNotificationRows

Add logs for NSSL traversal removal of transient group child ExpandableNotificationRows. These logs track when the transient views for group child ExpandableNotificationRows are cleaned by NSSL's traversal cleaning (when the Shade's collapsing finishes).

Bug: 281628358
Test: `adb shell settings put global systemui/buffer/NotifRenderLog
VERBOSE` and look for NotificationStackScroll tag in logcat
