List View Settings Permits Attach_Image field in list view, While customize doctype forbids checking the in_list_view box for attach image fields.

Description of the issue

I was configuring manufacturer logos to show in list view, I added a small client side script and configured my list view settings through the GUI, and everything worked perfectly.

Later when attempting to customize the manufacturer doctype, I noticed the validation error

"'In List View' is not allowed for field Logo (logo) of type Attach Image"

I can see here in the list view settings, when adding a field to the list view, only no value fields are forbidden to be added. https://github.com/frappe/frappe/blob/develop/frappe/public/js/frappe/list/list_settings.js#L325

Yet in the doctype validation code, no value fields are added as black listed fields in the list view, and then arbitrarily attach_image is black listed https://github.com/frappe/frappe/blob/develop/frappe/core/doctype/doctype/doctype.py#L1794

There is a conflict, in 1 place attach_image fields are blacklisted from appearing on the list view, and in the other place, its fine.

I suggest modifying the one line in https://github.com/frappe/frappe/blob/develop/frappe/core/doctype/doctype/doctype.py#L1794 to remove attach_field a
