sm6375-common: power-libperfmgr: ADPF: fix abnormal high uclamp

Browse source 
"GPU completion" task inherits a high uclamp value from RenderThread.
But it's not in the ADPF thread list, so it remains a high uclamp value.
Use SetTaskProfiles("ResetUclampGrp") and
SetTaskProfiles("NoResetUclampGrp") to manage the uclamp_fork_reset for
tasks.
