RFR: 8273185: Rename the term "atomic" in ReferenceProcessor [v2]

[Thomas Schatzl]

> Hi all,
> 
>   please review this suggestion to rename the term "atomic" in the `ReferenceProcessor` class to "concurrent"/"stw" to avoid the confusion with Atomic operations.
> 
> It's a smaller change than expected, which is good, but also might question the need for this change. I grepped for "atomic" in the reference processor sources and hopefully got everything.
> 
> Testing: tier1-5
> 
> Thanks,
>   Thomas
