Subject: AAC encoder metadata improvement

AAC-Encoder

   - Introduce metadata support for parametric stereo audio object type.
     Write metadata matrix mixdown coefficient only for channel config 5 and 6.
     Modified file(s):
        libAACenc/src/aacenc_lib.cpp

   - Revise metadata encoder downmix gain and fix matrix mixdown coefficient.
     Modified file(s):
