MDEV-23753: SIGSEGV in Column_stat::store_stat_fields
only collect persistent stats for columns explicitly listed
by the user in the ANALYZE TABLE PERSISTENT FOR COLUMNS (...)
clause. The engine can extend table->read_set as much as
it wants, it should not affect the collected statistics.
Test case from the 3b94309a6c applies - it used to crash,
because ha_partition extended table->read_set after the loop that
initialized some objects based on bits in the read_set but before the
loop that used these objects based on bits in the read_set.
