tools/power turbostat: Eliminate unnecessary data structure allocation

Linux core_id's are a per-package namespace, not a per-node namespace.

Rename topo.cores_per_node to topo.cores_per_pkg to reflect this.

Eliminate topo.nodes_per_pkg from the sizing for core data structures,
since it has no role except to unnecessarily bloat the allocation.

Validated on multiple Intel platforms (ICX/SPR/SRF/EMR/GNR/CWF) with
various CPU online/offline configurations and SMT enabled/disabled
scenarios.

No functional changes.
