Original commit message:
Fix Bug#53046 dict_update_statistics_low can still be run concurrently on same table

Replace the array of mutexes that used to protect
dict_index_t::stat_n_diff_key_vals[] with an array of rw locks that protects
all the stats related members in dict_table_t and all of its indexes.
