AAC decoder: enable set/get of DRC parameters during decoding

Enable setting/getting the following parameters at runtime (after
decoder creation):
KEY_AAC_DRC_TARGET_REFERENCE_LEVEL
KEY_AAC_DRC_TARGET_ATTENUATION_FACTOR
KEY_AAC_DRC_TARGET_BOOST_FACTOR
KEY_AAC_DRC_TARGET_HEAVY_COMPRESSION
KEY_AAC_DRC_EFFECT_TYPE
KEY_AAC_ENCODED_TARGET_LEVEL
