[Release] Fix binary name for downstream compatibility (#3752)

As of Sep 14, the torch-mlir binary
[wheels](https://github.com/llvm/torch-mlir-release/releases/tag/dev-wheels)
got renamed to `torch-mlir-core` from `torch-mlir`:
![image](https://github.com/user-attachments/assets/152e4977-71ef-4f57-8757-6dc75f72b670)

This was an unintended side-effect of the recent change of
`TORCH_MLIR_ENABLE_ONLY_MLIR_PYTHON_BINDINGS=True`
(https://github.com/llvm/torch-mlir/pull/3711) which skips setting `NAME
= "torch-mlir"` in
[setup.py](https://github.com/llvm/torch-mlir/blob/main/setup.py#L226-L232).

To avoid having multiple downstreams fix their pip deps, this change
allows using the same `torch-mlir` name for binaries, and reserves a
separate `torch-mlir-ext` name for the (less popular) binaries with
extensions enabled.
