8316046: x64 platforms unecessarily save xmm16-31 when UseAVX >= 3

[JornVernee]

See JBS issue. We don't need to save xmm16+ on x64 platforms (which are currently saved in FFM upcall stubs). This is achieved simply by adding these registers to the volatile register lists of both ABIs.

Related: #15688

Testing: jdk_foreign
