Update xTaskGetIdleTaskHandle() For SMP (#868)

Browse source 
* Update xTaskGetIdleTaskHandle() in SMP

This commit updates xTaskGetIdleTaskHandle() for SMP in the following ways:

- xTaskGetIdleTaskHandle() no longer accepts xCoreID argument in SMP so that
there is not change in API between single-core and SMP
- xTaskGetIdleTaskHandle() now returns the Active idle task handle in SMP,
which matches the behavior in single-core.
- Added xTaskGetIdleTaskHandleForCore() in SMP which accepts an xCoreID
argument. This function can be used to obtain the Passive idle task handles.

* Update xTaskGetIdleTaskHandle
