[Lens] Adds dimension name to datatable column meta information

[stratoula]

Describe the feature:
Part of #78277

In order to support alerting on expressions a new adapter has been added to inspector, to which every function producing a render output type should log the received datatable decorated with information about dimensions.

We would like to do for Lens what already has been done for the visualize editor. (need to pass to the adapter the dimensions meta) Here is the corresponding PR #107265

This can be done as part of the unification of the expressions. The only tricky part must be the xy charts that use the multitable, something that we will discuss during the unification of the xy charts. #116736

With the unification of the renderers among visualize and Lens, this has been done. I am closing this.
