text: Title: Add scope_name field when doing bulk ipam.prefixes imports
  Body: ### NetBox version
  
  v4.2.2
  
  ### Feature type
  
  Change to existing functionality
  
  ### Proposed functionality
  
  Add `scope_name` in addition or as alternative field to `scope_id` when doing builk `ipam.prefix` (and others) imports.
  
  ### Use case
  
  Before updating from v4.1 to v4.2 we noticed the breaking change about the removal of the `site` field which got replaced by a combination of `scope_type` and `scope_id`.  I don't question the need for the multipe scope types, but to have a better migration when doing bulk imports it would be nice to have a `scope_name` field in addition to `scope_id`. Of course you can only have one field filled (id or name).
  
  Sure this would cause an id-lookup when scope_name is used (like in v4.1) but it would help the transition (we would just have to add scope_type=dcim.site and rename the csv field site to scope_name and continue instead of using numeric ids during mass imports.
