[BlueZ,1/2] transport: Expose DelayReporting on MediaTransport interface

Commit Message

Arkadiusz Bokowy Oct. 26, 2024, 7:14 p.m. UTC

Exposing DelayReporting property on the MediaTransport interface will
allow media application to get the information about the delay reporting
feature during the SetConfiguration call in a similar way the profile
UUID and transport codec are provided. Otherwise, the application would
need to check the associated endpoint which might not be convenient.
