Wishlists federation support

[jbachelet]

Is your feature request related to a problem? Please describe. b2c-crm-sync, as of today, is providing customer federation. Now that the B2C customer has a record in core, it would add a lot of value to provide personalized and behavioral B2C Commerce data within the Core Platform. The customer's address book has been synced, now is time for Wishlists

Describe the solution you'd like Having wishlists synced the same way as the Address book would make sense. This would mean supporting both Salesforce Connect and custom LWC solutions, so that everyone, depending on his/her license, can leverage this feature.
