The LLVM dialect no longer has its own vector types. It uses `mlir::VectorType` everywhere. Remove `LLVM::getFixedVectorType/getScalableVectorType` and use `VectorType::get` instead. This commit addresses a [comment](https://github.com/llvm/llvm-project/pull/133286#discussion_r2022192500) on the PR that deleted the LLVM vector types.
