Currently PowerHAL does not distinguish between system processes and apps when deciding whether to apply universal boost. This patch distinguishes system sessions and app sessions and ignores system ones, making the disabling of universal boost dependent on the presence of app hint sessions. Bug: b/230511824 Test: manual Change-Id: I08dea29b3a45f2ba69ed99a9f188fa83ba143423
