chore(block)!: remove desktop BlockContact function for parity

Needed for status-im/status-desktop#16640

In Desktop, we still used a "forked" version of the BlockContact function that had as differences that it didn't leave the chat nor delete the messages.

However, we want to have parity now and those features, so it makes no sense to use a different function.

This is a breaking change because it removes an API, but I took care of removing the use of that function in the Desktop app and Mobile never used it, so it's an inoffensive breaking change.

Additionally, I added the notifications to the messenger response.
