Add a new special app access screen for long background tasks.

This new screen shows apps that hold the new RUN_LONG_JOBS permission. Also add a reference to this screen in an app's info page under the "Advanced" section for apps that have requested this permission. Bug: 255821578 Test: atest AppFilterRegistryTest Test: make -j RunSettingsRoboTests \ ROBOTTEST_FILTER="LongBackgroundTasksDetailsTest| LongBackgroundTasksDetailsPreferenceControllerTest" Test: visually via the Settings page Change-Id: Idc498e52d29abc6df757c35e8bc91f00de92ba4a
