Before this commit, it wasn't easy to find a demo product template that opens either with the product configurator or with the matrix from a list view.

To fix that, this commit appends '(CONFIG)' to the name of all demo product templates that open with the product configurator and '(GRID)' to all demo product templates that open with the matrix.

- Remove Attribute Values menu to ease onboarding because everything can be done
  more cleanly through Attributes menu.
- Remove unwanted new lines from help texts.
- Hide color fields when attribute type is not color.
- Move Attribute "Related Products" into a tab because it is less important than
  the rest of fields.

The opportunity is also taken to rename the `type` field of `product.attribute`
to `display_type` to better convey its meaning.

There are too many image sizes. Since they are stored resized this takes time to
generate when saving a new image, it's more rows on the attachment table, more
files on the disk, ...

64px is close enough to 128px that it can be removed without a big impact on
download size.

It will even reduce download and number of requests when both images are
displayed because now only one has to be downloaded and then benefit from cache.

The difference between the two is typically around 1.5kB which is negligible
these days, especially when the request overhead is around 0.5kB already, not
even taking into account other factors such as latency.

If a 64px image must absolutely be returned, it is still possible to pass the
size parameters to the image route. But the current guideline is to handle
resizing in the views when necessary.

Views
=====

- remove width and height attributes when existing CSS rules are overriding them
  (eg. `.oe_kanban_avatar` in the right context)
- add CSS rules instead of width and height attributes when possible
- use `object-fit: cover;` where width and height are forced to avoid distortion
  of non-square images
- for products, use `object-fit: contain;` instead, keep ratio but without crop
- add new CSS rules where the expected size was max 64px*64px before due to the
  image size itself
- remove `img-fluid` where using size classes to avoid conflicting rules

* = sale, website_sale, website_sale_comparison

Purpose
=======

This allows to handle use cases such as grape varieties for wine products where
multiple values need to be set for the same attribute, but they are all
informative and should not generate a choice or variants.

The general logic that existed previously is kept:
- multiple attribute lines on a product behave as an AND between them
- multiple values on a line behave as an OR between them

Example
=======

To generate 2 variants, with one possible value for each:
Line A: val 1, val 2

To generate 1 variant, with both informative values on it:
Line A: val 1
Line A: val 2

Technically
===========

- remove the constraints that prevented this use case from working since the
refactoring done in the previous commit removed the ambiguity when two
different lines have the same value
- update the product and comparison views accordingly

Extra
=====

- make the attribute category translatable and improve its list view
