[jdk17u-dev] RFR: 8278893: Parallel: Remove GCWorkerDelayMillis [v3]

[Richard Reingruber]

> This backport is a dependency for the backport of https://bugs.openjdk.org/browse/JDK-8310031
> Applies cleanly.
> No risk: only unused debug code is removed.
> 
> Local CI Testing:
> The fix passed our CI testing (e.g. 2024-02-23): JTReg tests: tier1-4 of hotspot and jdk. All of Langtools and jaxp. JCK, SPECjvm2008, SPECjbb2015, Renaissance Suite, and SAP specific tests (also with ParallelGC).
> Testing was done with fastdebug builds on the main platforms and also on Linux/PPC64le.
