Add |legacy_destination_url| back to SessionMessage for EME

Recent changes to CDM_7 removed |destination_url| as it is no longer
used in the EME spec. However legacy applications using the prefixed
EME API depend on it, so adding it back in so that it is available
to those applications.

BUG=448242
TEST=existing EME tests pass + Play movies play
