[14.0][IMP] shopfloor, stock_picking_partner_note: display picking info notes in cluster_picking and checkout scenarios

[sebalix]

Re-opening of #839

Depends on:

• [14.0][MIG] stock_picking_partner_note: Migration from 16 to 14.0 stock-logistics-workflow#1504

Stock picking partner notes are notes that are pre-defined for each customer
and can be displayed for each picking.
With this PR, we send them to the frontend for the cluster picking scenario and display them where needed.

This PR also deprecated shopfloor_packing_info in favor of stock_picking_partner_note, which is now used for both checkout and cluster picking.
