Alexander Markov 6195ea86bc [vm] Remove irregular type arguments parameter from factories 
In the VM, factory constructors always had an extra "type arguments"
parameter, even if class is not generic. Factory constructor bodies
were using class type parameters instead of function type parameters.

This results in extra code when calling non-generic factories
which is slightly inefficient in terms of code size and performance.
Also, it creates an additional complexity throughout the system as
factories should be special cased in many places.

This change removes artificial "type arguments" parameter, treating
factory constructors basically as static methods. This matches
kernel AST representation.

TEST=ci
