MDEV-35000: dict_table_close() breaks STATS_AUTO_RECALC

stats_deinit(): Replaces dict_stats_deinit().
Deinitialize the statistics for persistent tables,
so that they will be reloaded or recalculated
on a subsequent ha_innobase::open().

ha_innobase::rename_table(): Invoke stats_deinit() so that the
subsequent ha_innobase::open() will reload the InnoDB persistent
statistics. That is, it will remain possible to have the InnoDB
persistent statistics reloaded by executing the following:
RENAME TABLE t TO tmp, tmp TO t;

dict_table_close(table): Replaced with table->release().
There will no longer be any logic that would attempt to ensure
that the InnoDB persistent statistics will be reloaded after
FLUSH TABLES has been executed. This also fixes the problem that
dict_table_t::stat_modified_counter would be frequently reset to 0,
whenever ha_innobase::open() is invoked after the table reference
count had dropped to 0.

dict_table_close(table, thd, mdl): Remove the parameter "dict_locked".
Do not try to invalidate the statistics.

ha_innobase::statistics_init(): Replaces dict_stats_init(table).
