platform/x86/amd/pmf: Introduce AMD PMF testing tool for driver metrics and features

This tool leverages amd-pmf ioctls exposed via the util layer, allowing
validation of its newly integrated util layer and /dev/amdpmf_interface.
It includes a user-space test application, test_amd_pmf, designed to
interact with the PMF driver and retrieve relevant metrics for the
testing and analysis.

It provides definitions for test metrics, feature IDs, and device states,
and includes tests for various AMD PMF metrics such as power source, skin
temperature, battery state, and custom BIOS inputs/outputs. It also
enables the testing of PMF metrics data and feature support reporting.
