Do this by making them part of an MPVMainEncContext; the MPVEncContexts
still retain their pointers to access them.
(These tables are quite big, so that putting them in the MpegEncContext
would have been very wasteful for all the decoders using said structure.
But this is no longer a problem: MPVMainEncContext is only used by
encoders and allows to directly share the tables when slice-threading
is in use.)
