After CL[1], the client might be waiting forever when
system server throw Exception. The expected behavior
after throwing an Exception from the system server
should let the caller crash.

To keep the previous behavior, support exception as a
valid result for ResultCallback.

Currently, only the top-most activity of a root task can be resumed,
no matter how many descendant tasks or their windowing modes are.

Resuming the top activities of all visible and focusable leaf tasks
to be more flexible and can support features like app-pairs.

Therefore, Task#mResumedActivity is now set at leaf task vs. root task.
And Task#getResumedActivity() now returns the resumed activity of the
top-most leaf task. Same as Task#mPausingActivity.
