MDEV-24017: Blackhole : Specified key was too long; max key length is 1000 bytes
The maximum innodb key length is 3500 what is hardcoded in
ha_innobase::max_supported_key_length()). The maximum number of innodb indexes
is configured with MAX_INDEXES macro (see also MAX_KEY definition).
The same is currently implemented for blackhole storage engine.
Cherry picked from percona-server 0d90d81c3c507a6b1476246a405504f6e4ef9d4d
