[Bangtian Liu]

https://github.com/bangtianliu created https://github.com/llvm/llvm-project/pull/131393

We found the build broken using msvc debug build as below:
```
C:\Users\bangtliu\iree\third_party\llvm-project\llvm\include\llvm/ADT/SmallVector.h(1162): error C2338: static_assert failed: 'You are trying to use a default number of inlined elements for `SmallVector<T>` but `sizeof(T)` is really big! Please use an explicit number of inlined elements with `SmallVector<T, N>` to make sure you really want that much inline storage.'
C:\Users\bangtliu\iree\third_party\llvm-project\llvm\include\llvm/ADT/SmallVector.h(1162): note: the template instantiation context (the oldest one first) is
C:\Users\bangtliu\iree\third_party\llvm-project\llvm\include\llvm/ADT/SmallVector.h(1194): note: see reference to class template instantiation 'llvm::CalculateSmallVectorDefaultInlinedElements<T>' being compiled
        with
        [
            T=`anonymous-namespace'::LinalgOperandDef
        ]
C:\Users\bangtliu\iree\third_party\llvm-project\mlir\tools\mlir-linalg-ods-gen\mlir-linalg-ods-yaml-gen.cpp(120): error C2976: 'llvm::SmallVector': too few template arguments
C:\Users\bangtliu\iree\third_party\llvm-project\llvm\include\llvm/ADT/SmallVector.h(1195): note: see declaration of 'llvm::SmallVector'

```

This PR is added to address this error.
