cleanup: delete message-relayer

The `message-relayer` was a legacy server that
was responsible for relaying withdrawals. It has
not been maintained and is no longer used as part
of the devnet system. Keeping it around adds
additional maintainance burden for the team, especially
as things like 2 step withdrawals require it to be
refactored.
