This commit: - moves the "Company Registry Number" from `res_company` to `res_partner` (which might be different from the VAT in some localizations). This must be unique among all partners of the same country. - allows the search of partner by using their "VAT" or their "Company Registry Number" Task-id: 2857253 Community PR: odoo#91938 Enterprise PR: odoo/enterprise#27605 Upgrade PR: odoo/upgrade#3570 closes odoo/odoo#91938 Signed-off-by: Quentin De Paoli <qdp@odoo.com>
