Bluetooth: SAP: Add framework changes to support SAP. 

Bluetooth SIM access server (SAP) profile APIs added to the
framework APIs. As SAP server supports only disconnection
of SAP profile level connection this API is implemeted
along with other APIs.

It registers bluetooth state changed callback with the
adapter service,once there is a change in the bluetooth
state,it will bind/unbind the SAP service which is
implemented in BluetoothExt.APK.

SAP service, and other SAP Application layer is implemented
in BluetoothExt.APK.
