8294916: Cancelling a request must eventually cause its response body subscriber to be unregistered

[GoeLin]

I backport this for parity with 17.0.17-oracle.

the change itself applied clean. The tests needed some
changes to work:

test/jdk/java/net/httpclient/CancelStreamedBodyTest.java
A new test that lacks the changes of later change JDK-8295944
that was already backported.

test/jdk/java/net/httpclient/SmallTimeout.java
The test calls close() of ExecutorService which is a method
introduced after jdk17. I implemented the functionality
locally in the test.
