Fix and refactor ExpressionCodegen#pushClosureOnStack

- change Closure parameter to ClassDescriptor, load closure in the beginning
- invert and rename boolean parameter, also use it only to prevent pushing
  dispatch receiver (not the extension receiver) onto the stack because the
  only non-trivial usage of it is preceded by manual handling of the dispatch
  (not extension) receiver. This fixes innerOfLocalCaptureExtensionReceiver.kt
