test: add AVTP audio data path tests

Browse source 
Add 10 Phase 6 tests for the AVTP audio data path:
- IEC61883 and AAF packet structure layout validation
- 802.1Q frame header construction
- PDU size calculations for various audio configurations
- Ringbuffer audio data round-trip integrity
- Ringbuffer wrap-around with multiple PDU-sized writes
- IEC61883 receive simulation (packet → ringbuffer)
- IEC61883 transmit PDU construction and field verification
- Ringbuffer overrun detection
- Sequence number and DBC counter wrapping

These tests validate the AVTP packet formats and audio data path
logic without requiring hardware, AF_PACKET sockets, or CLOCK_TAI.
