Include only the Basic Capability for AVDTP GetCapabilities response

AVDTP GetCapabilities request should return only the Basic
Capabilities, as defined in the AVDTP 1.3 spec.
Otherwise, returning a capability such as Delay Reporting would
result in some remote devices droping the AVDTP connection

Also:
 * Print SEP protocol service capabilities per Stream Control
   Block when dumping the state to a bugreport
 * Add extra log messages

Bug: 77668253
Test: Manual: connect with Momentum M2 Headset and examine the
      AVDTP GetCapabilities response.
