This PR continues the work of https://github.com/llvm/llvm-project/pull/171775 by moving more useful types/attributes into MLIRPythonSupport. You can now do ```c++ struct PyTestIntegerRankedTensorType : mlir::python::MLIR_BINDINGS_PYTHON_DOMAIN::PyConcreteType< PyTestIntegerRankedTensorType, mlir::python::MLIR_BINDINGS_PYTHON_DOMAIN::PyRankedTensorType> struct PyTestTensorValue : mlir::python::MLIR_BINDINGS_PYTHON_DOMAIN::PyConcreteValue< PyTestTensorValue> ``` instead of `mlir_type_subclass` and `mlir_value_subclass`; **specifically manual registration of the "value caster" via indirection through the Python interpreter is no longer necessary** . You can also now freely use all such types at the nanobind API level (e.g., overload based on `FP*`): ```c++ using mlir::python::MLIR_BINDINGS_PYTHON_DOMAIN; standaloneM.def("print_fp_type", [](PyF16Type &) { nb::print("this is a fp16 type"); }); standaloneM.def("print_fp_type", [](PyF32Type &) { nb::print("this is a fp32 type"); }); standaloneM.def("print_fp_type", [](PyF64Type &) { nb::print("this is a fp64 type"); }); ``` Note, here we only port `PythonTestModuleNanobind` but there is a follow-up PR that ports **all** in-tree dialect extensions https://github.com/llvm/llvm-project/pull/174156 to use these. After that one we can soft deprecate `mlir_pure_subclass`. Note, depends on https://github.com/llvm/llvm-project/pull/171775
