In Android P, we only show "Battery saver" and "Power management"
in battery settings. So we need to remove other preferences.
Keep "Battery percentage" toggle for now because it is not
cross-listed in other places.

This cl adds the basic structure for battery tip:
1. BaseBatteryTip: Model class to represent the tip and build
preference and dialog
2. SummaryTip: Display a general battery summary(i.e. your battery
is good..)
3. BatteryTipLoader: AsyncLoader to load the battery tips.
4. BatteryTipPreferenceController: preference controller for
preference group to display battery tips
This cl also:
1. Remove the anomaly code in PowerUsageSummary and we will add it
to app restriction in future.
2. Add preference_category_no_title.xml to avoid the extra 32dp
blank at the top.

Create PowerUsageSummaryLegacy and power_usage_summary_legacy, which
contains the old implementaion.
