[IMP] uom/saas~18.1: remove uom categories and product packagings

To adapt for the changes made in odoo/odoo#184131 and
odoo/enterprise#72206, this PR applies the following changes:

• Product Packagings that have the same name and quantity are merged
  into one uom_uom record and applied on all the products that had
  those packagings applied. Their corresponding barcodes are also
  preserved and applied on those products using the new model
  product.uom.
• UoMs that belonged to the same category will have their
  relative_uom_id set to the reference unit of that category.
• Every product will have all the units in the same category of its base
  unit addded to the new field uom_ids, so that they can be used in
  sale orders, pickings, etc.
• All the fields related to product packagings in all models are
  removed.
• Removal of uom_uom fields that are mentioned in the community PR.
• Remove usage of uom_uom.rounding field.
