Allow granular settings for notifications

Is your feature request related to a problem? Please describe.

This feature was requested by Neil Gaiman.

I'd love to easily get to a version of Bluesky Notifications that doesn't have likes, reposts and follows, and just has things people have written. I think I miss too much in the scrolling.

While the Mentions feed does satisfy some of this, it might be nice for users with a high follower count to be able to disable notifications of certain events.

Describe the solution you'd like

Add a Settings/Notifications screen.

Display a check box for each type of notification.

Only create notifications for event types which were selected by the user.

This is similar to #1079

This doesn't directly solve this issue as you would still receive the notifications, but FYI there's a draft PR open to add a Mentions tab to the Notifications screen:
