FEATURE: allow user to override watched_precedence_over_muted setting (#22340)

Recently, site setting watched_precedence_over_muted was introduced - https://github.com/discourse/discourse/pull/22252

In this PR, we are allowing users to override it. The option is only displayed when the user has watched categories and muted tags, or vice versa.
