Update MIME types in AidlConversion and MediaDefs

Add some IANA-listed types that were absent from MediaDefs.
Also add unlisted types that have corresponding
android.media.AudioFormat.ENCODING_* constants in the Java SDK.

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.
