MDEV-16703: Update AUTO_INCREMENT in the UPDATE statement

Browse source 
Currently RocksDB engine doesn't update AUTO_INCREMENT in the UPDATE statement.
For example,

CREATE TABLE t1 (pk INT AUTO_INCREMENT, a INT, PRIMARY KEY(pk)) ENGINE=RocksDB;
INSERT INTO t1 (a) VALUES (1);
UPDATE t1 SET pk = 3; ==> AUTO_INCREMENT should be updated to 4.

Without this fix, it hits the Assertion `dd_val >= last_val' failed in
myrocks::ha_rocksdb::load_auto_incr_value_from_index.
