[FIX] web: multi-hell-ditable list

only activate multi-edit on list with specific attribute.
When the attribute multi_edit="1" is set on the tree view the user
can select a/some records and it will activate the multi-edit
with confirmation dialog (even for a single record).
Also, on-change are not applied when using multi-edit

closes odoo/odoo#37525
