Function calls have silent dependencies

Original issue in AI was a duplicate of 📌 Add module dependencies to tools Active which has been done!

I have erred on the side of caution with the DownloadFilefromUrl function, which requires the file module to be enabled if the option is selected to save the downloaded file as a Drupal file entity, but there are strong arguments to be made either way for that.

Thanks Paul, for the Download functions, we will soon hopefully have an abstraction layer for that, so it should just have to check that one downloader exists, similiar to how we have default chat for instance and then based on that run.

Looks good, getting merged.
