Bump LLVM to get bazel fixes (#2517)

The last llvm bump in https://github.com/llvm/torch-mlir/pull/2511
pointed to
b44b3494f6,
however the bazel build upstream was not clean at this point:

```

The bazel fixes followed in a subsequent commit at
28b27c1b10.
This PR bumps LLVM by a few more commits (to include the bazel fixes)
which helps restore Torch-MLIR's bazel build back to 🟢 .
