Bump DynamicPPL.jl, AdvancedVI, and Bijectors version (#1979)

* bump dppl test versions

* also bump bijectors

* bump AdvancedVI versions

* revert Bijectors bump

* bumped vi and bijectors too

* breaking change

* removed refernce to Bijectors.setadbackend

* fixed VI

* remove testing of Tracker.jl

* relax prior tests a bit
