The actual output power of the Thread device may be determined by both the Thread radio chip and the FEM. Consider the output power error of the Thread radio chip and the gain error of the FEM, the actual output power is inconsistent with the expected output power. To guarantee that the actual output power is accurate and meet the regulatory requirements, the output power should be calibrated in the factory if the output power is not accurate. This commit contains the following changes: - Adds a power calibration implementation - Adds a config file to configure the target power for different countries - Adds a tool for the factory to persist the power calibration data
