This patch adds runtime check of AVX512 on running machine and update avx512 support for xbzrle_encode_buffer function to accelerate xbzrle encoding speed.
The runtime check is added in meson.build and meson_options.txt. The updated AVX512 algorithm is provided in ram.c, xbzrle.h and xbzrle.c. The test code is provided in test-xbzrle.c.
