Add a new Bluetooth device details page
Bug: 35877479 Test: make RunSettingsRoboTests The existing behavior is to bring up a dialog with Bluetooth device details with checkboxes for each supported profile. This adds a new page that serves the same purpose with a switch for each profile and a footer containing the MAC address. Whether to use the new page or old dialog is controlled by a flag accessible via BluetoothFeatureProvider. Change-Id: I026c363d4cd33932a84017a67cbef51c258bad10
