Add form count to fields menu in Admin

I have a number of fields that were previously in use but no longer are, as well as some similar fields that are reused across different forms that may not be the best fit.

The form lookup feature on the field detail page is helpful for identifying fields that can be deactivated as well as seeing which fields may be overused.

It would be helpful if a count of the forms the fields are used on was a column that could be shown on the fields list in the Admin Center.
