Add function to return list of Org items linking to item at point

This function is not meant for interactive use, but instead should be used in
source blocks such as


This will add a table of all items linking to the current item at point, and cut
be used in item templates, for example.

Background: I tried to achive this functionality with `org-ql` directly, but
somehow failed.  This function simply encapsulates the corresponding call to
`org-ql-query`, adding the ID property of item at point automatically.
