RFR: 8346712: Remove com/sun/net/httpserver/TcpNoDelayNotRequired.java test

[Matthias Baesken]

Here [JDK-8333864](https://bugs.openjdk.org/browse/JDK-8333864) it has been discussed that the test TcpNoDelayNotRequired.java is not giving us much benefit these days so it could be removed.
>From 8333864
"I suppose we could remove this test, and label the original issue as noreg-perf. The test does nothing but verify that its run time is below a certain threshold anyway."
