MDEV-23370 innodb_fts.innodb_fts_misc failed in buildbot, server crashed in dict_table_autoinc_destroy

This issue is caused by MDEV-22456 ad6171b9. Fix involves the backported version of 10.4 patch
MDEV-22778 5f2628d1 and few parts of
MDEV-17441 (e9a5f288).

dict_table_t::stats_latch_created: Removed

dict_table_t::stats_latch: make value member and always lock it for
simplicity even for stats cloned table.

zip_pad_info_t::mutex_created: Removed

zip_pad_info_t::mutex: make member value instead of pointer

os0once.h: Removed

dict_table_remove_from_cache_low(): Ensure that fts_free() is always
called, even if dict_mem_table_free() is deferred until
btr_search_lazy_free().

InnoDB would always zip_pad_info_t::mutex and
dict_table_t::autoinc_mutex, even for tables are not in
ROW_FORMAT=COMPRESSED nor include any AUTO_INCREMENT column.
