[Adapt] Implement Device Service Search(SDP) & event handling

This patch implements Service Search API
in bt-service, OAL and Bluetooth HAL layer.

In order to maintain consistency with other open source stack,
after services are received as single property from OAL, rest of
the device properties are also fetched from stack and one single
event is sent to BT frwk containing all services along with
other bonded device informations.
