Sergei Golubchik 22b3ba9312 MDEV-25102 UNIQUE USING HASH error after ALTER ... DISABLE KEYS ...

on disable_indexes(HA_KEY_SWITCH_NONUNIQ_SAVE) the engine does
not know that the long unique is logically unique, because on the
engine level it is not. And the engine disables it,

Change the disable_indexes/enable_indexes API. Instead of the enum
mode, send a key_map of indexes that should be enabled. This way the
server will decide what is unique, not the engine.
