dptf: Add support for Running Average Power Limits
This change adds support for emitting the PPCC table, which describes the ranges available as knobs for DPTF to tune. It can support min/max power, min/max time window for averaging, and the minimum adjustment size (granularity or step size) of each power limit. The current implementation only supports PL1 and PL2.
