[Bug Fix] "Dock defend string and tips in settings are incorrectly" issue

Symptom: After the dock defend was triggered, the battery tips still
show "Future-Bypass" dock defend mode. It should be the "Active" dock
defend mode.

Root Cause: The original `BatteryInfo.isBatteryDefender` was implemented
by using `longlife`, due to the charging limit also reuse `longlife`
issue, we replace the implementation of `BatteryInfo.isBatteryDefender`
with HAL API call `isTempDefend` and `isDwellDefend`. However, the
dock defend also needs `longlife`, the original
`BatteryInfo.isBatteryDefender`. So the dock defend checking failed
after replacing the implementation of `BatteryInfo.isBatteryDefender`

Solution:
- Add new property isLonglife in BatteryInfo
- Replace all isBatteryDefender reference that needs isLonglife
