RFR: 8255562: delete UseRDPCForConstantTableBase [v4]

[Hohensee, Paul]

I updated the CSR Specification to make it more clear:
-----
Remove

product(bool, UseRDPCForConstantTableBase, false,
"Use Sparc RDPC instruction for the constant table base.")

and make it obsolete in JDK 16 and expired in JDK 17.
-----

Lgtm as well.

Thanks,
Paul
