Adds a complete multi-xlayer encoding pipeline for AV2. A single avmenc invocation can now encode multiple extended layers (xlayers), each optionally containing embedded layers (mlayers), and assemble their outputs into combined temporal units. Use cases include:

  • texture+alpha
  • stereo
  • subpicture tiling
  • spatial scalability

…pport

Implement a complete multi-xlayer encoding pipeline for AV2, enabling
independent encoding of multiple extended layers (xlayers) with their
outputs assembled into combined temporal units (TUs).
