Fix battery optimization display problems

Root cause:
RequestIgnoreBatteryOptimizations adds package in
PowerWhitelistManager#addToWhitelist for intent
Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS.

Settings UI uses PowerAllowlistBackend to check if
an APP is in power allow list. Each UI component should
PowerAllowlistBackend#refreshList() or UI will get
a stale result.

Solution:
This change fixes below display problems by refreshing
allow list from DeviceIdleController service.

1. Battery optimization summary in Battery usage details.
2. Battery optimization list.

BYPASS_INCLUSIVE_LANGUAGE_REASON=I need the object name
to describe the root cause.
