[mlir][linalg] Use `ub.poison` in linalg vectorizer instead of `0` for some transfer ops (#146544) This patch is a follow up to https://github.com/llvm/llvm-project/pull/146088 and changes the padding value in the linalg vectorizer from `0` to `ub.poison` in `vector.transfer_read`s created for extracting slices or when vectorizing a generic.
