MDL-49257 grades: introduce calculation freeze
In order to prevent changes in the existing grades when we fix bugs
we are introducing the gradebook code versioning. Each course may
"freeze" the code version to the older date. Freezing is usually done
during upgrade or restore and can be removed by the teacher by pressing
the button and accepting potential grade changes. There is no visible
setting and not possible to change the version back manually.
See MDL-50432 and MDL-50522
