Support accessibility for battery usage in U (1)

Fix b/265746746: TalkBack doesn't have any feedback after the actual double-tap of day bar and bi-hourly bar.

When users double clicked a time slot in battery usage chart with TalkBack on, jump the accessibility focus to the app list category title to let users know what happened after click.
