Qualify NoneType as mlir::NoneType in recordToType to avoid ambiguity when other headers introduce a different NoneType symbol. This fixes build failures seen when enabling tblgen-to-irdl in certain downstream configurations The ambiguity is between: [llvm::Nonetype](https://github.com/intel/llvm/blob/sycl/llvm/include/llvm/ADT/None.h#L26) and [mlir::Nonetype](https://github.com/llvm/llvm-project/blob/main/mlir/tools/tblgen-to-irdl/OpDefinitionsGen.cpp#L125) Both are visible due to `using namespace mlir` and `using namespace llvm` in the file. Fixes: https://github.com/llvm/llvm-project/issues/160537

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Getting the Source Code and Building LLVM
