power: Add a debug property for switching powerhint.json path

Browse Source 
Add a bool property `vendor.powerhal.config.debug`.
Power HAL would use `/data/vendor/etc/powerhint.json` when vendor.powerhal.config.debug = true.

Bug: 206061061
Test: adb wait-for-device root; adb shell mkdir -p /data/vendor/etc/;
      adb push powerhint_mod.json /data/vendor/etc/powerhint.json
Test: adb shell setprop vendor.powerhal.config.debug true && \
      adb shell getprop vendor.powerhal.config.debug && \
      adb shell stop vendor.power-hal-aidl && \
      adb shell start vendor.power-hal-aidl && adb shell stop && adb shell start
Test: adb pull /data/local.prop ; vim local.prop
      + vendor.powerhal.config.debug=true
