MDEV-11429 Increase number of max table_open_cache instances

Browse Source 
Increase max number of possible table_open_cache instances from 512K
to 1024K. This only affects user who are trying to set the variable over
the old limit.

Delete not used test table_open_cache_instances_basic
(Need to be added back and rewritten in 10.2)
