Add a check whether an A2DP codec is supported before including it

Some of the A2DP SRC or SNK codecs might not be supported if the
corresponding shared library is not included.
Don't include such codecs when configuring and registering
the stream end points on the local device.

Bug: 112839060
Test: Manual - remove A2DP codec shared libraries and check the
      returned AVDTP Capabilities
