x86-64: Add memset family functions with 256-bit EVEX

Update ifunc-memset.h/ifunc-wmemset.h to select the function optimized
with 256-bit EVEX instructions using YMM16-YMM31 registers to avoid RTM
abort with usable AVX512VL and AVX512BW since VZEROUPPER isn't needed at
function exit.

(cherry picked from commit 1b968b6b9b3aac702ac2f133e0dd16cfdbb415ee)
