Inconsistent `attributes` handling

These are initial fixes. Note that haven't gone through all the components yet.
Unsure items, not used or will break backward compatibility, ie. subtheme needs to be updated:

• comment
• field
• field-comment
• fieldset
• nav
• node

Backward incompatible tracking for subtheme:
- templates/field/image.html.twig

- restored image functionality when passing src directly

Standardize all components implementation, use a unique `COMPONENT_attributes`, which can be passed `attributes` as needed.

If you do that, you will have both COMPONENT_attributes and attributes in your template.

It seems you have another problem to fix, probably in the way your are calling the components.

For example, instead of doing that:

{%
  include 'radix:image' with {
    image_attributes: attributes,
    responsive: true,
  }

You may need to use the only keyword:

{%
  include 'radix:image' with {
    attributes: attributes,
    responsive: true,
  } only

Thanks a lot ckng, merged.
Pierre I'll check and see what we can do.
