Add quickUpdate method to BatteryHeaderPrefCtrl

This cl adds a method called quickUpdateHeaderPreference, which will
update the following items immediately without waiting for the
BatteryInfo:
1. Battery level
2. Battery charging status(whether to show lighting bolt)
3. Clear the charging summary

Note: this cl doesn't optimize the BatteryInfo loading time.

This cl also rename "TimeText" to "BatteryPercentText" because in
new UI that textview is used to display battery percentage.
