AccessControl: Add accesscontrol metadata to datasources DTOs (#42675)

* AccessControl: Provide scope to frontend

* Covering datasources with accesscontrol metadata

* Write benchmark tests for GetResourcesMetadata

* Add accesscontrol util and interface

* Add the hasPermissionInMetadata function in the frontend access control code

* Use IsDisabled rather that performing a feature toggle check
