this can now be found in the sidebar View panel
- this uses existing 'lock_camera_and_layers' but renames the property to 'use_local_camera'
- uses RNA_def_property_boolean_negative_sdna to flip the value
- remove the local view code in rna_SpaceView3D_lock_camera_and_layers_set
- update Python code
- update Addons code will be separate commit
Fixes T60756
