[NI] Prototype for SAM-conversion.

Supported:
- conversion in resolution parts. Also sam-with-receiver is supported automatically
- separate flag for kotlin function with java SAM as parameters

TODO:
- fix overload conflict error when function type is the same byte origin types is ordered
- consider case when parameter type is T, T <:> Runnable
- support vararg of Runnable

[NI] Turn off synthetic scope with SAM adapter functions if NI enabled
