Ensure activity configuration when applying WCT with display change

This fixes two cases:
1. Because WOC#applyTransaction always defers visibility(config) update,
the ensureActivitiesVisible in ATMS#ensureConfigAndVisibilityAfterUpdate
is always no-op, if there are non-top visible activities, their
configuration won't be delivered to clients in time.
E.g. Launch a translucent task and rotate device, then if the activity
behind is slow to relaunch, it may flash back content.

2. ATMS#ensureConfigAndVisibilityAfterUpdate always updates config for
top activity. When rotating display with split-screen, the WCT also
contains the operation to set task bounds. Then it will cause redundant
activity relaunch.
