power-libperfmgr: Send LOAD_RESET on hint session creation

Replace current init behavior with a reset hint. This makes sense,
because creating a session is implicitly a "load reset" plus HWUI may
not always send a reset hint after its background refactor. This will
also reduce first-frame boost latency for new sessions.
