Describe changes:

  • adds gunzip transform
  • adds zlib_deflate transform (maybe we can find a better name)

SV_BRANCH=OISF/suricata-verify#2882

#14674 with fix for in-place transforms : not all zlib manage to do decompress in-place
So, transform must check if the input and output buffer is the same, and use a temporary buffer if needed
