RFR: 8294047: HttpResponseInputStream swallows interrupts [v5]

[Darragh Clarke]

> Currently if a `HttpResonseInputStream` gets interrupted while reading it will just swallow the exception and continue,
> 
> This PR changes it to close the stream and throw an IOException, I added a test to cover this which just uses two threads to read the stream then interrupt it.
