demux_cue: deprecate --demuxer-cue-codepage for --metadata-codepage

What are cue sheets not metadata or something? No reason this needs to
be a separate option so just deprecate it. This does mean that the
default value changes from "auto" to "utf-8" for this obscure fringe
case. I really hope people don't use non-UTF-8 cuesheets, but the next
commit will change the default of --metadata-codepage to "auto" so
there's no actual change in behavior to users.
