Fixes #27059
Description
In 6.0 we started uniquifying check constraint names if there was a conflict in the database, but we also started adding a prefix to all names that didn't have a prefix that we recognized.
This was unexpected and unnecessary, so we decided to revert the prefixing change.
Customer impact
Users get a new migration changing all the check constraint names that don't follow the pattern. The workaround is to manually add overriding configuration for each check constraint.
How found
Customer report on 6.0.
Regression
Yes, From 5.0
Testing
Already present.
Risk
Low; only affects migrations. Also added quirk to revert to previous behavior.
