[Bluetooth] Retrieve L2CAP features mask on connection setup
The Bluetooth 1.2 specification introduced a specific features mask value to interoperate with newer versions of the specification. So far this piece of information was never needed, but future extensions will rely on it. This patch adds a generic way to retrieve this information only once per connection setup.
