service: Add IPCHandlerBinder

This CL integrates Binder IPC into the daemon. This introduces
IPCHandlerBinder and BluetoothBinderServer which is the Binder server
proxy for IBluetooth. A new command-line switch is introduced to
optionally disable Binder on platforms that do not use it.

BluetoothBinderServer currently does not fully implement any of the IPC
calls and consists of stubs.
