[zlib] Rewrite deflate_fuzzer: cover more configs, stream the input
Zlib has a lot of parameters that can be used for deflate compression.
This makes the fuzzer cover a much larger set of them.
It also streams the input in an attempt to cover more interesting code
paths.
I have verified that this allows the fuzzer to hit the issues in the
first two linked bugs. Let's see if it finds something else too :-)
