stdlib: Add Wattson TPU power estimation (#5022)

Introduces a multi-dimensional TPU power model for Wattson, integrating
frequency, cluster, and parallel request concurrency.

Key changes:
- Created a non-linear TPU power curve LUT with support for
workload-based scaling.
- Implemented TPU frequency and cluster extraction from 'DVFS' tracks.
- Clamped request lookups to 8 for now due to measurement limitations.

Bug: 454625451
Test: Wattson power estimation vs ground truth
