[performance] cache mute check results (#4202)

This separates our the user mute handling from the typeconverter code, and creates a new "mutes" filter type (in a similar vein to the visibility filter) subpkg with its own result cache. This is a heavy mix of both chore given that mute calculation shouldn't have been handled in the conversion to frontend API types, and a performance bonus since we don't need to load and calculate so many things each time, just the single result each time with all necessary invalidation handled by database cache hooks.
