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.
