Description:
The MySQL server version number is stored in the DD tablespace upon server initialization. When upgrading to a newer version, the version number must be updated upon successful completion of the upgrade.

How to repeat:
Initialize 8.0.11. Restart with 8.0.12 to complete upgrade, restart again with 8.0.12. Inspect the version number df.server_version in fil_ibd_open() for tablespace 'mysql'.

Suggested fix:
Add handlerton functions for set/get access. Update the version number upon successful completion of upgrade.
