Usage of ha_delete_table()

df01249... by Sergei Golubchik

optimize ha_delete_table_force

first try discovering engines, then the rest.
otherwise every DROP TABLE non_existent; will do
lots of i/o trying to remove .MYI/.MYD/.MAI/.MAD/.CSV/etc files

this matches the old behavior where DROP TABLE always tried to discover
the table before dropping.

replace HTON_AUTOMATIC_DELETE_TABLE with return -1 from drop_table()

e785dff... by Sergei Golubchik

rewrite bug#26704 test case

drop-no_root needs DROP DATABASE to fail.
But `chmod 000` is not reliable after drop table force anymore.

Make DROP DATABASE to fail by creating an extra file in the db dir

MDEV-11412 Ensure that table is truly dropped when using DROP TABLE

don't do table discovery on DROP. DROP falls back to "force"
approach when a table isn't found and will try to drop in all
engines anyway. That is, trying to discover in all engines before
the drop is redundant and may be expensive.

Other things:
- synced code in mysql_rm_table_no_locks() with mariadb-10.7.4

4daf7ac... by Sergei Golubchik

introduce hton->drop_table() method

first step in moving drop table out of the handler.
todo: other methods that don't need an open table

for now hton->drop_table is optional, for backward compatibility
reasons

Update ma_delete_table.cc to be able to handle drop force

Original patch from Amazon, with some fixed test results

MDEV-28078 Garbage on multiple equal ENUMs with tricky character sets

TYPELIBs for ENUM/SET columns could erroneously undergo redundant
hex-unescaping at the table open time.

Fix:
- Prevent multiple unescaping of the same TYPELIB
- Prevent sharing TYPELIBs between columns with different mbminlen
