RFR: 8327286: Obsolete unused NUMAPageScanRate product option [v2]

[Thomas Schatzl]

> Hi all,
> 
>   please review making the flag `NUMAPageScanRate` obsolete.
> 
> This option controlled some fairly esoteric performance capability for Solaris; Solaris support has been removed in JDK 15, and the last remaining reference to the option (which was a no-op) in JDK 22.
> 
> Please also look at the CSR.
> 
> Testing: local compilation, grepping sources, starting the VM with that option to see that the message shows up.
> 
> Thanks,
>   Thomas
