Reland "bluetooth: Add an alternate BluetoothDeviceClient"

This is a reland of 0a4fe769ca5f9253698d755f65d538b4190fea34

The original CL was reverted because it was causing a crash on Linux.
Before this fix, we assumed that object_manger_ would always be present.
This is not true on Linux, where the BluetoothDeviceClient is created
but not Init'ed. This reland fixes the issue by first checking if
object_manager_ is present.
