CLEANUP: task: move the cpu_time field to the task-only part

Browse Source 
The CPU time accounting field called "cpu_time" is used only by tasks
and not tasklets, yet it used to be stored into the TASK_COMMON part,
which doesn't make sense and wastes tasklet memory. In addition, moving
it to tasks also helps better group the various parts in cache lines.
