[Backend] Adding the ability for a user to delete one/multiple profiles

[jrainville]

Description

Backend sibling of #9807

We need to hook to the status-go API and add the functions and signals/events in Nim.

Acceptance Criteria

• The Nim functions are available to call the delete API
• The Nim signals back to the UI that one of the profiles was deleted (model update)
• If the UI is ready before this, hook to the UI, if not, use placeholders
