MDEV-22199 Add VISIBLE attribute for indexes in CREATE TABLE
This was done to make it easier to read in dumps from MySQL 8.0 generated
with MySQL workbench
Remove usage of deprecated variable storage_engine. It was deprecated in 5.5 but
it never issued a deprecation warning. Make it issue a warning in 10.5.1.
Replaced with default_storage_engine.
- Moved tests depending on utf8 characters from create to create_utf8
- Fixed some tests in create and sp that wrongly tried to create table
from non existing table on existing table. In a later patch we may
first check if table exists, in which case the error message would
change.
- Updated results for partition_debug_tokudb
