Update zlib 3rd party code to v1.2.11

zlib source code, version 1.2.11. https://www.zlib.net/.

Include all the gynmastics involved in:
- making sure we compile zlibstat and set the output files locations and filename to those expected by the starshatter setup.
- turning off the ASM includes as they are invalid for the new versions of zlib (and crash when running).
- matching the calling conventions of the Starshatter code by ommiting ZLIB_WINAPI from the zlib preprocessor defines.
- fix debug build compile error in zlibstatic:

This fixes some string warnings.
