Relax SurfaceFlinger cpuset and adding uclamp.min for RenderEngine

SurfaceFlinger IPC improved with mid and big cores, relaxing cpuset will
help improve its efficiency. For render engine, we set uclamp.min to
skip scheduling on little cores.

FWIW, we let the RT scheduler figure out what is good for perf/power.
