Fixed point conversions of files entropy_decoder.c, ivas_stereo_eclvq_dec.c,... 

Fixed point conversions of files entropy_decoder.c, ivas_stereo_eclvq_dec.c, ivas_sns_com.c, ivas_stereo_eclvq_com.c

[x] data type and operator changes in entropy_decoder.c
[x] res_bpf_adapt() converted to fixed point implementation.
[x] ivas_stereo_eclvq_dec.c - BASOP updates.
[x] functions present in ivas_sns_com.c converted to fixed point.
[x] functions present in ivas_stereo_eclvq_com.c converted to fixed point.
    Absolute diff of dumps
      for, res_buf: 0.007217%
      for, res_global_gain: 0.009206%
[x] Fixed warnings in ivas_qmetadata_dec functions and integrated ivas_omasa_decode_masa_to_total_fx function call.
