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.

An out-of-tree MLIR dialect
This is an example of an out-of-tree MLIR dialect along with a standalone opt-like tool to operate on that dialect.
Building
This setup assumes that you have built LLVM and MLIR in $BUILD_DIR and installed them to $PREFIX. To build and launch the tests, run
mkdir build && cd build
cmake -G Ninja .. -DMLIR_DIR=$PREFIX/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$BUILD_DIR/bin/llvm-lit
cmake --build . --target check-standalone
To build the documentation from the TableGen description of the dialect operations, run
cmake --build . --target mlir-doc
Note: Make sure to pass -DLLVM_INSTALL_UTILS=ON when building LLVM with CMake in order to install FileCheck to the chosen installation prefix.
