Add page for choosing calendar & reply for event modes.

Also adds the link to set trigger behavior to the main mode page (only for calendar so far), and the switch preference to enable/disable automatic rules (for all but manual DND mode).

Removes the "escape hatch" to allow manual mode to also use the new modes pages.

Ported from ZenModeEventRuleSettings.

Flag: android.app.modes_ui
