refactor(stock): convert PR get_invoiced_qty_map to qb aggregate

Browse Source 
Replace the raw `select pr_detail, qty from Purchase Invoice Item` (summed in
Python) with a frappe.qb GROUP BY Sum(qty) per pr_detail, matching the sibling
get_returned_qty_map. Same result on MariaDB; valid under Postgres. Covered by
the existing make_purchase_invoice tests.
