Throw error for 32-bit archs

Closes #10002

WebAssembly is a 32-bit arch. Pyodide includes XGBoost and is having trouble updating to CPython 3.12 due to being unable to update XGBoost.

#8964 looks like it was trying to fix 32-bit errors.

@henryiii I filed #10021 to restore 32-bit support.

Thanks! By the way, it's not too hard to build in Pyodide in CI as a way to test 32-bit builds. NumPy and others do it, see https://github.com/numpy/numpy/blob/main/.github/workflows/emscripten.yml or https://github.com/scikit-hep/boost-histogram/blob/develop/.github/workflows/emscripten.yaml (the later example gets the pinned values from pyodide rather than having to update several values every time something changes!). Don't know if it's helpful.
