[Meta] Implement Send & Receieve capabilities for Close Remote Tab

[skhamis]

Closing tabs remotely has been completed on Desktop and Android and the Sync team wants to implement on iOS. Link to the Sync Epic: https://mozilla-hub.atlassian.net/browse/SYNC-4089

I think the best way to go about this is to split the send & receive into separate PRs as that'll make it easier to review and reason about (sending will have significantly more UX to cover).

[ ] Ability to receive close tab commands from other devices
[ ] Ability to send and undo close tab commands to other devices
[ ] Notifications when receiving close tab commands and deeplinking to the closed tabs when notification is tapped

Sammy Khamis can you clarify what is the ask for the iOS Team? Also, I think we should take a look and fix this one https://mozilla-hub.atlassian.net/browse/FXIOS-9315 ( https://mozilla-hub.atlassian.net/browse/FXIOS-9315|smart-link ) before moving forward with the closing tabs. Happy to chat more about it. Thanks!

Norberto Andres Furlan, I’ll update the issue to make it clearer but the Sync team will be working on the implementation of this. The main ask of the iOS team is advice/feedback on the PRs that will be coming through! Thanks for linking that bug, we’ll make sure it’s properly prioritized with the rest of the teams work!
