Rather than handling zlib handling manually, use find_package from CMake to find zlib properly. Use this to normalize the LLVM_ENABLE_ZLIB, HAVE_ZLIB, HAVE_ZLIB_H. Furthermore, require zlib if LLVM_ENABLE_ZLIB is set to YES, which requires the distributor to explicitly select whether zlib is enabled or not. This simplifies the CMake handling and usage in the rest of the tooling. This is a reland of abb0075 with all followup changes and fixes that should address issues that were reported in PR44780.
