Minor improvements for the multivariate MCV lists
The MCV build should always call get_mincount_for_mcv_list(), as the there is no other logic to decide whether the MCV list represents all the data. So just remove the (ngroups > nitems) condition. Also, when building MCV lists, the number of items was limited by the statistics target (i.e. up to 10000). But when deserializing the MCV list, a different value (8192) was used to check the input, causing an error. Simply ensure that the same value is used in both places. This should have been included in 7300a699, but I forgot to include it in that commit.
