feat(sale): Add product search by supplier info

This commit introduces the `sale_product_supplierinfo_search` module, which allows users to search for products on sales order lines and in the global product catalog by using the vendor's product code or product name.

Key features:
- Overrides `_name_search` on `product.product` to extend search capabilities.
- Activates the extended search via a context key on the sales order line.
- Adds a user-friendly "Search in Vendor Info" filter to the main product search view.
- Modifies the search result display to include the vendor's product code for better user context.
- Includes comprehensive unit tests to validate the new functionality.
- Provides OCA-compliant documentation and demo data.
