sm6375-common: power-libperfmgr: Ignore system hint sessions for universal boost
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
