MDEV-26294 Duplicate entries in unique index not detected when changing collation 

ha_innobase::check_if_supported_inplace_alter(): Refuse to change the
collation of a column that would become or remain indexed as part of
the ALTER TABLE operation.

In MariaDB Server 10.6, we will allow this type of operation;
that fix depends on MDEV-15250.
