MDEV-27605 ALTER .. ADD PARTITION uses wrong partition-level option values

Browse Source 
When a partition with engine-defined partition options is added by
ALTER, it shows the correct definition in SHOW CREATE, but the actual
values get inherited from the previous partition.

The cause of the bug is that the server did not parse the options
associated with the newly added partition.

In the case of ALTER, the complete part_info, which represents the
partition structure after ALTER, is built by prep_alter_part_table().
So, we need to parse engine-defined partition options after the call
of the function.
