Describe your motivation

Given that https://github.com/vaadin/hilla/issues/3131 aims to add better support for downloading files and data, it would be nice to support file-type columns in AutoGrid, for use cases like PDF invoices in an orders grid.

Describe the solution you'd like

When an entity has a field of a certain type, the AutoGrid should be able to show a link that activates the download of a file.
