LOG: Reland: [GPUToXeVMPipeline][Pipeline] Modify pipeline to add `convert-vector-to-llvm`. (#169573)

`convert-vector-to-llvm` pass applies a set of vector transformation
patterns that are not included in the standard `convert-to-llvm` pass
interface. These additional transformations are required to properly
lower MLIR vector operations. Since not all vector ops have direct
`llvm` dialect lowering, many of them must first be progressively
rewritten into simpler or more canonical vector ops, which are then
lowered to `llvm`. Therefore, running `convert-vector-to-llvm` is
necessary to ensure a complete and correct lowering of vector operations
to the `llvm` dialect.
