Pull Request Title: fix: Dashboard Chart to support Child Table Doctype.
Pull Request Description:

ISSUE: If we select a Child Table Doctype in Dashboard Chart for e.g. Sales Invoice Item. Filter for that Dashboard Chart doesn't work.

SOLUTION: Added a new field parent_document_type in Dashboard Chart which will be visible if document_type selected is a child table. Filter was not working because for the selected document_type read permissions were checked and for the child table we do not have any permissions, Now we can use parent_document_type to check read permission.
