xbzrle_encode_buffer function to accelerate xbzrle encoding speed.

The runtime check is updated in meson.build and meson_options.txt.

The updated AVX512 algorithm is provided in ram.c, xbzrle.c and
xbzrle.h.

The test code is provided in test-xbzrle.c.

I think this v3 and previous v3 are identical except for mthe link to
the previous discussion.

Hi, Juan, 
     You are right, this v3 and previous v3 are identical except the link to previous discussion. The previous [patch v3 0/2] was sent failed as shown in my mail, so I resend this patch. Sorry for the ambiguity of resending same patch, and thanks for your time ~

Best Regards
Ling
