Description of the issue/feature this PR addresses:

Accessibility improvements forbids the use of the syntax
`<i class="fa fa-check"/> Some text`
to create a labelled icon. But, by this, some fonts are changed.

Desired behavior after PR is merged:
The old syntax can be used.

Today, Odoo is really tricky to use without seeing the screen, it must be improved to be usable.

This PR forbid to use labels without a "for" attribute, add some title, rule and aria attributes in HTML. With that, Odoo will be fully usable with a screen reader.

Purpose
=======

In POS, it is hard-codded in such a way that grouping will be done for the
uom category that has database id == 1.

Specification
=============

We have solved this issue: we have added a new boolean field in the uom category form view that

If a user chooses this option then products having that uom category will be grouped in the POS.

Both uom category Unit and Weight have been set to groupable by default.

- Removed the hardcoded part of groupable for uom which had database id == 1,
  Now grouping will be done on 'groupable' field of "product.uom", which is
  related to the field of the same name on "product.uom.category".
- Only the `Unit` uom category is grouped by default
