Support concrete type projection wiring

[neko-kai]

After #741 distage loses the ability to wire type projection bindings like this:

class Path {
  class A
}

val module = new ModuleDef {
  make[Path#A]
  make[Path]
}

Injector()
  .produceUnsafe(module, GCMode.NoGC)
  .get[Path#A]

This will currently fail to compile because of a bad constructor being generated at make[Path#A]. Constructor macros in izumi.distage.constructors.* should be altered to take into account non-value prefixes and summon them accordingly, i.e. instead of generating this constructor:

{ () => new Path#A }

generate this constructor:

{ (path: Path) => new path.A }

I guess we may just throw a readable error message and not spend time on implementing support for deprecated projections.
