4867 multiple mac addresses (#17902)

* Create MACAddress model and migrations to convert existing .mac_address fields to standalone objects

* Add migrations

* All views/filtering working and documentation done; no unit tests yet

* Redo migrations following VLAN Translation

* Remove mac_address filter fields and add table columns for device/vm

* Remove unnecessary "bulk rename"

* Fix filterset tests for Device

* Fix filterset tests for Interface

* Fix tests on single-object forms

* Fix serializer tests

* Fix filterset tests for VMInterface

* Fix filterset tests for Device and VirtualMachine

* Move new field check into lookup_map iteration

* Fix general MACAddress filter tests

* Add GraphQL types/filters/schema

* Fix bulk edit/create tests (bulk editing Interfaces will be unsupported because of inheritance from ComponentBulkEditForm)

* Make mac_address read_only on InterfaceSerializer/VMInterfaceSerializer

* Undo unrelated work

* Cleanup unused IPAddress derived stuff

* API endpoints

* Add serializer objects to interface serializers

* Clean up unnecessary bulk create forms/views/routes

* Add SearchIndex and adjust indexable fields for Interface and VMInterface

* Reorganize MACAddress classes out of association with DeviceComponents

* Move MACAddressSerializer

* Enforce saving only a single is_primary MACAddress per interface/vminterface

* Perform is_primary validation on MACAddress model and just check if one already exists for the interface

* Remove form-level validation

* Fix check for current is_primary setting when reassigning

* Model cleanup

* Documentation notes and cleanup

* Simplify serializer and add ip_addresses

* Add to VMInterfaceSerializer too

* Style cleanup

* Standardize "MAC Address" instead of "MAC"

* Remove unused views

* Add is_primary field for bulk edit

* HTML cleanup and add copy-to-clipboard button

* Remove mac_address from Interface and VMInterface bulk-edit forms

* Add device and VM filtering

* Use combined assigned_object_parent in table to match structure of IPAddressTable

* Add GFK fields to MACAddressSerializer

* Reorganize "Addressing" sections to remove from proximity to "Device Components" and related groupings

* Clean up migrations

* Misc cleanup

* Add filterset test

* Remove mac_address field from interface forms

* Designate primary MAC address via a ForeignKey on the interface models

* Add serializer fields for primary_mac_address

* Update docs
