  [mlir][vector] Add operations used for Vector distribution

Add vector op warp_execute_on_lane_0 that will be used to do incremental
vector distribution in order to target warp level vector programming for
architectures with GPU-like SIMT programming model.
The idea behing the op is discussed further on discourse:
