[ref-using-main][non-BE][split-non-BE] Resolve "Update MC CLDFB-Domain HRTFs"

• Related issues: #588 (closed)
• Requested reviewers: @millsa

Reason why this change is needed

• Use same conversion method for fastconv MC HRTFs like in #584 (closed)
• Complexity reduction when using 3 instead of 5 taps

Description of the change

• Update/add new Matlab script for SD HRIRs
• Reduce BINAURAL_NTAPS to 3 as well
• Redefine BINAURAL_NTAPS_SBA to BINAURAL_NTAPS since they now share the same value
• Update tables in ROM
• Update binaural_renderers_hrtf_data for loading into the codec
• Verify changes

Affected operating points

• Bitstream compatibility: 1. Produced bitstream is BE compared to previous state
• Non-BE: Only binaural rendering (not room) operating points with fastconv are affected
