UserTopic: Set visibility_policy or delete UserTopic row without error.

This commit updates 'set_user_topic_visibility_policy_in_database'
to not raise an error when deleting a UserTopic row and the user
doesn't have a visibility_policy for the topic yet, or when setting
the visibility_policy to its current value.

Also, it includes the changes to not send unnecessary events
in such cases.

## Changes in Zulip 7.0
**Feature level 169**

Trying to mute a topic that is already muted or unmute a topic
that was not previously muted now results in a success response
rather than an error.
**Feature level 168**
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
