Fix compatibility of CapturedTypeConstructor and NewCapturedTypeConstructor

Now both of those classes implements one interface with `TypeProjection`
  property. That allows old captured type approximator use new captured types.

That change fixes tests related to diagnostics:
- SETTER_PROJECTED_OUT
- DEBUG_INFO_UNRESOLVED_WITH_TARGET
- UNRESOLVED_REFERENCE_WRONG_RECEIVER

Also `typeProjection` property renamed to `projection` according to naming in NI.
