Overwrite the gauge capacity with the backup one if the gauge capacity
reset to nominal.
Test: fake /sys/class/power_supply/bms/charge_full to nominal and
check if it can be restored from /persist/battery/qcom_charge_full

The code was only allowing the Learned Capacity to decrease while
QCOM FG learned capacity may actually go up for some reasons.
Ensure we use the FG learned capacity on update and always restore
the saved one on boot.

Test:
- delete file /persist/battery/qcom_charge_full
- adb logcat to check code flow related health@2.0
- adb bugreport
- no "avc: denied" on health vendor service
- check learned capacity in both
/sys/class/power_supply/bms/charge_full
/persist/battery/qcom_charge_full
-- decrease /sys/class/power_supply/bms/charge_full
to check backup to /persist/battery/qcom_charge_full
-- increase /sys/class/power_supply/bms/charge_full
to check restore from /persist/battery/qcom_charge_full
(simluate the reset condition)
