Moves workload monitoring logic from microkernel server file and
relocates it so it resides with other workload monitoring code.
This change means that the various variables use for workload monitor
computations no longer need to be globally visible.
This move also allows correction of two pre-existing issues:
1) Eliminates reference to non-existent POWERSAVEOFF configuration
option.
2) Test to see if idle task has been deselected is no longer done
if prior test has shown that it has just been selected, since
the two conditions are mutually exclusive.

no changes are required for ARC architecture support, which does not
