Add method to get source location of Inventory Routes

This technical module extends the stock.route model to add the method _get_source_location(dest_location). It recursively traces upstream rules (pull or pull_push) from a destination location, and returns the ultimate source location — stopping at a rule with procure_method='make_to_stock' or when no applicable pull rules remain.

Useful for multi-hop route setups (e.g., warehouse → packing → output), to programmatically determine the actual stock source. No UI changes are made — it's purely for custom logic or other technical modules.

Example usage:

route = env.ref("stock.route_warehouse0_mto")
dest = env.ref("stock.stock_location_customers")
src = route._get_source_location(dest)
print(src.display_name)
