Add and revise traces in window manager

- Change internal traces to window manager tag (excluding
  ActivityMetricsLogger because it may be used by existing parser).
- Add traces for the main operations of activity on server side.
- Give a name for the Runnable which runs in animation thread
  (the trace tag of "android.anim" looper is enabled) so it is
  easier to understand the action from trace.

Test: 1. adb shell atrace --async_start wm
      2. Launch and finish an activity
      3. Check output of "adb shell atrace --async_stop"
