Conversion and integration of MC-Param, SBA and MASA encoder paths 

[x] init functions for mc_param (open, close ,reconfig)
[x] bw_detect_fx, ivas_get_spar_md_from_dirac_fx, pca_enc functions, requantize_direction_EC_3()
[x] Conversion changes related to masa metadata direction alignment, detect framing async
[x] Q info addition
