MAP: Fix bugs in SDP search result handling

* Without any SDP record indicating support for 1.1 and 1.2, the default
  version for MAP-event-report XML message should be 1.0 instead of 1.2
* Support for various MAP features should consider both local and remote
  MapSupportedFeatures bit mask
* Move handling of MapSupportedFeatures in BluetoothMapContentObserver
  to one place
