[partition] Move initLayout logic to object PartitionLayout

- The logic of the method initLayout belongs to the object
  PartitionLayout. Move logic to that object.
- Use a single method initLayout in object PartitionCoreModule.
- Member m_partLayout in object PartitionCoreModule is no longer
  allocated.
