[split-non-be] Resolve # 766 "Split-rendering missing in OMASA"

• Related issues: #766 (closed)
• Requested reviewers: @tyagiri @vaclav

Reason why this change is needed

Split rendering support is missing from OMASA.

Description of the change

Add split rendering support to OMASA:

• ISM_MODE_NONE, ISM_MASA_MODE_MASA_ONE_OBJ, and ISM_MASA_MODE_PARAM_ONE_OBJ use ParamBin for the rendering, and that supports split rendering already since last summer.

• ISM_MASA_MODE_DISC: MASA part is rendered with ParamBin into CLDFB. ISMs are rendered using ivas_td_binaural_renderer_sf_splitBinaural(), the time-domain poses are analysed into CLDFB, and the the components are mixed in CLDFB domain.

• ISM_SBA_MODE_DISC: temporal offset of object signals is changed.

Affected operating points

• No effect on bitstream.
• No effect on non split rendering modes
• Using split rendering output mode in the decoder with OMASA bitstream is now supported.
• Split rendering of OSBA-DISC is changed.
