camera power hint: add prefer high cap in all modes

Prefer high cap will choose the mid / high cores when possible with
consideration of energy efficiency.

Running task on high cores with low clock is more efficient than running
at little core with high clock.

This hint also addresses CTS issues with keeping latency_sensitive = 1.
(equivalent to prefer idle)

This hint adds:
1) Enable prefer_high_cap of camera vendor group
2) Set high_capacity_start_cpu to 4
4) Set MemFreq floor
5) Change camera-daemon/cpu.uclamp.latency_sensitive owner to root

Bug: 186564130

Test:
android.hardware.camera2.cts.RobustnessTest#testAeAndAfCausality (5/5)
android.hardware.cts.CameraTest#testPreviewCallback (5/5)
android.hardware.camera2.cts.CameraDeviceTest#testCameraDeviceRepeatingBurst (5/5)
android.hardware.cts.CameraTest#testFocusDistances (3/6). (3/6) without CL.
