[mlir python] Port in-tree dialects to nanobind. (#119924)
This is a companion to #118583, although it can be landed independently
because since #117922 dialects do not have to use the same Python
binding framework as the Python core code.

This PR ports all of the in-tree dialect and pass extensions to
nanobind, with the exception of those that remain for testing pybind11
support.

This PR also:
* removes CollectDiagnosticsToStringScope from NanobindAdaptors.h. This
was overlooked in a previous PR and it is duplicated in Diagnostics.h.

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 - Component Build

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.

Building - Monolithic Build

This setup assumes that you build the project as part of a monolithic LLVM build via the LLVM_EXTERNAL_PROJECTS mechanism. To build LLVM, MLIR, the example and launch the tests run

mkdir build && cd build
cmake -G Ninja `$LLVM_SRC_DIR/llvm` \
    -DCMAKE_BUILD_TYPE=Release \
    -DLLVM_TARGETS_TO_BUILD=host \
    -DLLVM_ENABLE_PROJECTS=mlir \
    -DLLVM_EXTERNAL_PROJECTS=standalone-dialect -DLLVM_EXTERNAL_STANDALONE_DIALECT_SOURCE_DIR=../
cmake --build . --target check-standalone

Here, $LLVM_SRC_DIR needs to point to the root of the monorepo.
