[jdk17u-dev] RFR: 8286171: HttpClient/2 : Expect:100-Continue blocks indefinitely when response is not 100

I would backport this as we currently do a larger effort of fixing http issues, and this is a bugfix that fits well into this task. It will make other backports planned more simple.

Clean backport.

To make the test work, I had to add test fixes from later changes that were already backported.
