The original default implementation for power.stats HAL did not have a
good example implementation of the power statistics related APIs. Adding
a new default implementation that gives a more informative example
Bug: 122267057
Test: run vts -m VtsHalPowerStatsV1_0Target
Test: adb shell "lshal debug android.hardware.power.stats@1.0::IPowerStats/default"
Observed the following output
========== PowerStats HAL 1.0 state residencies ==========
Entity State Total time Total entries Last entry timestamp
DefaultEntity Active 1 ms 2 3 ms
DefaultEntity Sleep 4 ms 5 6 ms
========== End of PowerStats HAL 1.0 state residencies ==========
