The log "Screen frozen for" is too rough to know how much time
the client windows spend. By adding the logs that are closer
to the entries of notify/response, it is easier to break down
the bottleneck of screen frozen time.
Also:
- Move log "Orientation start waiting" to after IWindow#resized.
So it is clearer to know when the redraw request is sent.
- Consolidate activityRelaunched to finishRelaunching because
the operation should belong to ActivityRecord.

Test: Rotate device and check log "finishDrawing".
