avcodec/me_cmp,dvenc,mpegvideo: Move ildct_cmp to its users

MECmpContext.ildct_cmp is an array of function pointers that are not set by ff_me_cmp_init(), but that are set by users to one of the other arrays via ff_set_cmp(). Remove these pointers from MECmpContext and add pointers for the actually used functions to its users. (The DV encoder already did so.)
