parser_service and serializer_service should probe zlib's memory footprint

[ashtum]

Currently we are using the suggested formula from zlib's documentation: https://github.com/cppalliance/http_proto/blob/cf22661f3e2811a328aec5e8574fe637017ac007/src/parser.cpp#L472-L480

However, it has the same issue mentioned in the documentation:

zlib's memory footprint can also be specified fairly precisely. It is larger for compression than for decompression, and the exact requirements depend on how the library was compiled.

The probe operation should be performed once during parser_service and serializer_service installation and should take into account all configuration parameters used for deflate and inflate.

You can just go back in the commit and get the probe code, it replaces the allocation functions in the z_stream with an implementation that performs measurements.
