Move fully drawn metric log out of wm lock

The method getPackageOptimizationInfo will access IO which
may spend 3~10+ms, so post the log action to the logger thread
to avoid blocking other important UI operations.

ActivityRecord#reportFullyDrawnLocked is removed because fully
drawn won't be accepted if the window is not drawn, so the
invocation reportActivityLaunched in it is a dead code.
Currently reportActivityLaunched will be called from
ActivityRecord#onWindowsDrawn.
