Change the order of compilation passes, transformation is made lazy at code gen (#8489)

* Ast no transformation
* Add getImplNoTransform to the macros module
* progress on delaying transf
* Fix methods tranformation
* Fix lazy lambdalifting
* fix create thread wrapper
* transform for lambda lifting
* improve getImplTransformed
* Fix destructor tests
