x86-64: Use ZMM16-ZMM31 in AVX512 memmove family functions

Update ifunc-memmove.h to select the function optimized with AVX512
instructions using ZMM16-ZMM31 registers to avoid RTM abort with usable
AVX512VL since VZEROUPPER isn't needed at function exit.

(cherry picked from commit e4fda4631017e49d4ee5a2755db34289b6860fa4)
