/**
 * Provides backward compatibility for settings by mapping old or new value types to the new type.
 *
 * Chat configuration service doesn't have great support for migrating settings between types.
 * This utility function helps to maintain backward compatibility when a setting's type changes.
 *
 * @param settingValue The setting value of the new type.
 * @param map A function that transforms the setting value (which can be either old or new type) to the new type.
 * @returns The mapped setting value of the new type.
