LOG: [MLIR][Vector] Test to accompany bug fix (#154434)

Bug introduced in 
https://github.com/llvm/llvm-project/pull/93664

The bug was fixed in
https://github.com/llvm/llvm-project/pull/152957

But there was no test. This PR adds a test that hits the assertion
failure if the fix is reverted (if I change dyn_cast to cast).

Added: 
    

Modified: 
    mlir/test/Dialect/Vector/transform-vector.mlir

Removed:
