MediaFormat: Add more audio MIME types

Browse Source 
Add audio MIME types that have corresponding
android.media.AudioFormat.ENCODING_* constants.

For the types related to MPEG4 audio use the convention described
in RFC 6381 where various codecs are specified using the Audio
Object Type Identifier from the ISO/IEC 14496-3 standard and its
amendments.

For the types related to MPEG-H audio use the identifiers from the
ISO/IEC 23008-3 standard.
