[PATCH v13 2/3] x86,/proc/pid/status: Add AVX-512 usage elapsed time

AVX-512 components use could cause core turbo frequency drop. So it's useful to expose AVX-512 usage elapsed time as a heuristic hint for the user space job scheduler to cluster the AVX-512 using tasks together. Tensorflow example: $ while [ 1 ]; do cat /proc/pid/status | grep AVX; sleep 1; done
