power: Handle launch and interaction hints for perf HAL platforms

 * MP-CTL does not handle POWER_HINT_INTERACTION and POWER_HINT_LAUNCH
   directly. Requests for processing are sent by Qualcomm BoostFramework
   (QPerformance) at the framework service level. Since we do not have
   BoostFramework, process POWER_HINT_INTERACTION and POWER_HINT_LAUNCH
   in PowerHAL to ensure a sufficient level of performance.
 * For proper operation, perfboostsconfig.xml file is required.
