Change Details

Once `wgCheckUserEventTablesMigrationStage` has been set to `SCHEMA_COMPAT_NEW`, the value can be assumed to always be `SCHEMA_COMPAT_NEW` and the configuration value removed. =======Acceptance criteria * [] Remove `wgCheckUserEventTablesMigrationStage` and update the code that uses it to assume that the value is `SCHEMA_COMPAT_NEW`

Once `wgCheckUserEventTablesMigrationStage` has been set to `SCHEMA_COMPAT_NEW`, the value can be assumed to always be `SCHEMA_COMPAT_NEW` and the configuration value removed. Code that supports the different migration stages should not be removed until {T366781} is complete. This means that this task should just substitute the value of `SCHEMA_COMPAT_NEW` in the relevant places and remove any code that is now unreachable. {T366783} will finish the removal of the relevant code. =======Acceptance criteria * [] Remove `wgCheckUserEventTablesMigrationStage` and update the code that uses it to assume that the value is `SCHEMA_COMPAT_NEW`
