Move coroutines to kotlin.coroutines package: compiler

Generate continuation type as kotlin.coroutines.Continuaion. This code will
fail at runtime since there is no stdlib backing this change yet.
However, in order to generate compatible stdlib we need a compiler, which
generates continuation type as kotlin.coroutines.Continuation.
Thus, firstly we support the change in the compiler, make it bootstrap
compiler and only then change stdlib and tests accordingly.
