Metrics: Log SDP attributes to statsd

* Log ProtocolDescriptorList's protocol version field to statsd
* Log BluetoothProfileDescriptorList's profile version field to statsd
* Log SupportedFeatures for A2DP, HFP, AVRCP, PBAP, MAP to statsd
* Log SDP metrics before we disconnect from L2CAP during SDP discovery
* Values are logged in small endian array
* Do this logging before we declare an SDP search is done

Bug: 112969790
Test: make, test drive with statsd
