LBAC for datasources: Move validation of rules from datasources to LBAC Rules (#94622)
* FIX: Remove the checks for lbac rules inside of datasources

* Remove json validation for lbac rules

* Preserve lbac rules in updates

* Refactored test to remove the table structure

* refactor: change to allow naming and concise override instead of complex branching

* refactor to make sure we set an empty field for updates

* bugfix

* check for datasources.JsonData

* fix merge

* add datasource to check for field presence only

* add function call for readability
