[Mlir-commits] [mlir] [MLIR] Install missing standalone helper tools (PR #205066)

[Momchil Velikov]

https://github.com/momchil-velikov created https://github.com/llvm/llvm-project/pull/205066

Standalone MLIR installs CMake package files that can reference helper executables needed by downstream builds. Most helper tools already have install paths available through existing LLVM tool and utility install options, but `mlir-src-sharder` does not pass an install destination to `add_tablegen` and `mlir-irdl-to-cpp` does not define an install rule.

Install those two missing helpers.

options, but mlir-src-sharder does not pass an install destination to
add_tablegen and mlir-irdl-to-cpp does not define an install rule.
