JDK-8222369 - ExecutableElement.getReceiverType returns null instead of NOTYPE
Description
Summary
-------

Fix `ExecutableElement.getReceiverType` to follow its specification and to return an object rather than null for "no type" results.

Problem
-------

In cases where the specification of `ExecutableElement.getReceiverType` required a sentinel object to be returned -- a `NoType` [type mirror](https://docs.oracle.com/en/java/javase/12/docs/api/java.compiler/javax/lang/model/type/NoType.html), with kind `NONE` -- the javac implementation returned `null`.

Solution
--------

Fix the implementation to follow the specification.

Specification
-------------

No specification change; behavioral change only.
Comments
Moving to Approved.
