Bazel configuration missing for Python bindings?

[tkocmathla]

I'm interested in using the torch-mlir python bindings in a project that uses Bazel as its build system. Based on the developer docs, it seems like the Bazel configs for torch-mlir are mostly focused on supporting torch-mlir-opt, and indeed I don't see any CAPI or Python binding rules in the main Bazel build file.

I think what's needed to do this is:

• The CAPI library (from torch-mlir-c/Dialects.h). This can be built with mlir_c_api_cc_library from @llvm-project//mlir:build_defs.bzl.
• The pybind11 extension library (from python/TorchMLIRModule.cpp).
• A tablegen rule to generate the Python wrapper code for ops (_torch_ops_gen.py).
• (Maybe) A convenience py_library that bundles the above and any MLIR Python dependencies.

There are examples of these in the MLIR project's Bazel file.

Is there interest in this from the maintainers? I'd be willing to contribute these changes if so.
