Allocates an ansnd voice per stream and configures/starts it in single-buffer mode (no continuous re-feed needed yet, matching the PSP/Linux single-shot approach). Real linear panning from directionality via left/right voice volume. ansnd has no polling API for voice state, so finish detection uses a voice_callback (fired from ansnd's own audio DMA interrupt, not the main thread) that sets a flag audioStreamDolphinIsFinished() reads. Links libansnd (new for this project) and wires duskdolphin/audio into the CMake build for the first time. Verified via the dusk-dolphin toolchain: both GameCube and Wii targets compile and link cleanly. Runtime verification in headless Dolphin was inconclusive - confirmed via an A/B test against a pre-audio baseline build that a pre-existing MMIO flood (unrelated to this change, reproduces identically with zero audio code present) keeps the harness from reaching the game's own steady state before timing out.
