Fix some animation janks during code start.

- Create a   summary placeholder for preferences with summary.
- Create a totally empty summary for prefernces without summary.
- For all dynamic prefs that has *no* SummaryLoader, add meta to set
their summary to empty.
- Other dynamic perfs has   as initial summary.

By doing this, all dynamic pref's height is fixed and will not change as
we update summaries, thus eliminating jank during cold start in each
page.

Also removed DashboardAlias for notification preference and default apps as a side fix.
