  [LibWebRTC] Enable AVX2 extensions only if host supports AVX2
https://bugs.webkit.org/show_bug.cgi?id=258708

Reviewed by Philippe Normand.

Include specialized AVX2 files in LibWebRTC only if the host supports
AVX2 extensions. Also, when AVX2 is enabled, avoid building using AVX512
extensions even if the host has support for it since it may result into
compatibility issues (binary built on host with AVX512 support but
executed in host without AVX512 support will result into a crash).
