When the kanban is grouped on a readonly fields,
it shouldn't be possible to drag and drop a record from
one column to another.
It was the case when the field was part of the view architecture,
but not when the fields wasn't part of the architecture,
despite we have the information as we have the field description
through the search view / the control panel.
This is a bug which has been introduced during the OWL conversion.
For instance, in 15.0, when grouping CRM leads by sanitized phone,
it wasn't possible to drag and drop records from one column
to another.
In master this is possible.
Besides, in the legacy code, the readonly information
is read from both the field in the architecture and the general
field descriptions:

In addition, compared to before,
this revision allows a new possibility compared to before:
Make draggable when grouped by a field which is by default
readonly in the model,
but which is set as `readonly="0"` in the view.
This is to be uniform with what is done in the list and form views.
