Send beatmap has to server on solo score request

Right now, the client does nothing to ensure a beatmap is in a valid
state before requesting to submit a score. There is further work to be
done client-side so it is more aware of this state (already handled for
playlists, but not for the solo gameplay loop), but the solution I have
in mind for that is a bit more involved.

This is not used server-side yet, but I want to get this sending so we
can start using it for some very basic validation.

Will resolve the basic portion of #11922 after implemented server-side.
