Sets update_all_types when setting mapping (#14002)

Prior to 5.6, we would push mappings once the object type was used. Since we are now ensuring all mappings are set, there is a situation where a field with type string exists but we are pushing text.

You can not have a field with the same name, but different data type, in two different document types.

To resolve this, we are setting update_all_types when updating mappings.
