drm/amd/display: Reduce Stack Usage by moving 'audio_output' into 'stream_res' v4

The function `dp_retrain_link_dp_test` currently allocates a large
audio_output array on the stack, causing the stack frame size to exceed
the compiler limit (1080 bytes > 1024 bytes).

This change prevents stack overflow issues:
amdgpu/../display/dc/link/accessories/link_dp_cts.c:65:13: warning: stack frame size (1080) exceeds limit (1024) in 'dp_retrain_link_dp_test' [-Wframe-larger-than]
static void dp_retrain_link_dp_test(struct dc_link *link,

v2: Move audio-related data like `audio_output` is kept "per pipe" to
    manage the audio for that specific display pipeline/display output path
    (stream). (Wenjing)

v3: Update in all the places where `build_audio_output` is currently
    called with a separate audio_output variable on the stack & wherever
    `audio_output` is passed to other functions
    `dce110_apply_single_controller_ctx_to_hw()` &
    `dce110_setup_audio_dto()` (like `az_configure`, `wall_dto_setup`)
    replace with usage of `pipe_ctx->stream_res.audio_output`
    to centralize audio data per pipe.

v4: Remove empty lines before `build_audio_output`. (Alex)
