[18.0][IMP] product_abc_classification: add multi-company support

[JordiMForgeFlow]

• ABC profiles are shared by default, but can be also company-specific.
• We check consistency between ABC profile company and the company of the products assigned to it.
• ABC classification product levels have company automatically computed: either company of the profile or company of the related product.

Depends on #2252 for being able to pass tests
