Missing modules (libcoremlpython) when importing coremltools 8.2 on linux

## 🐞Describing the bug
Coremltools 8.2 installs fine on Linux but errors with missing modules when imported. Looks like `libcoremlpython.so` is missing.
```
❯ python3 -c "import coremltools"
Failed to load _MLModelProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLCPUComputeDeviceProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLGPUComputeDeviceProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLNeuralEngineComputeDeviceProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLModelProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLComputePlanProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLModelProxy: No module named 'coremltools.libcoremlpython'
Failed to load _MLModelAssetProxy: No module named 'coremltools.libcoremlpython'
❯ find ./myenv/lib/python3.12/site-packages/coremltools -name "*.so"
./myenv/lib/python3.12/site-packages/coremltools/_deps/kmeans1d/_core.cpython-312-x86_64-linux-gnu.so
./myenv/lib/python3.12/site-packages/coremltools/libmilstoragepython.so
./myenv/lib/python3.12/site-packages/coremltools/libmodelpackage.so
```

I only see this only on Linux. On macOS, I can install and import coremltools 8.2 fine (I can see `libcoremlpython.so` in `/myenv/lib/python3.12/site-packages/coremltools/`).

Do you have any advice?

## System environment (please complete the following information):
- coremltools version: 8.2
- OS (e.g. MacOS version or Linux type): Linux jammy (22.04)
- Any other relevant version information (e.g. PyTorch or TensorFlow version): na

Reproduce with the reported Python 3.12 virtual environment and `python3 -c "import coremltools"`, then inspect the installed 8.2 manylinux wheel and its `coremltools` package contents. Compare the Linux installation with the macOS installation, where `libcoremlpython.so` is present; done means the Linux package contains the required module and imports without these errors.
