Make AvatarRenderedSizeFactor configurable and set it to 3 (#17951) 

Save a bit of bandwidth by only requesting 3-times the rendered avatar
size. Factor 4 is only really beneficial on a handful of mobile phones
and I don't think they are the primary device we design for.

Configurability contributed by zeripath.
