[6807][ADD] sale_order_secondary_unit_convert

QT6807

This module lets users enter sale order line quantities in a convenient input secondary unit while the line keeps being displayed in another secondary unit.

For example, a product may be handled internally in "Bundle" but sold to the customer in "Bag". Users can enter the quantity in "Bundle", and it is automatically converted so that the line shows the quantity in "Bag".

I will add translation when I find the approach is appropriate through reviewing.

@smorita7749 Please update the PR title. Seem like wrong.

@smorita7749 I failed to understand the usage of this module. Why we need a new secondary uom field for sale order line since we already have sale_order_secondary_unit module. Am I missing something?

Some products are managed with a base unit, kg and some secondary units, bundle and bag.
They receive POs in bundles, but they want to show the POs lines and invoices to their customers in bags, which means a conversion between secondary units is needed.

Originally, I thought the conversion should be on the wizard, but since it should be saved, I decided is should be on the lines.

Same as above.
