Add custom empty message to loop layouts

Object lists and tables have the ability to show a custom text + icon if the object set is empty.

The same I would love to have on a looped layout. Current workaround is to always use two sections, one containing the actual loop and another an empty object list purely for the purpose of showing the custom empty message. The section visibility is switched based on an object set is null check.

I know this is a small and simple ask, but it helps to streamline our building experience :wink:
