AmdWarpBlockScatterGather
struct AmdWarpBlockScatterGather[SmemType: DType, thread_layout: Layout, warp_tile_layout: Layout, simd_width: Int, is_a: Bool, warp_rows: Int, warp_cols: Int, swizzle: OptionalReg[Swizzle] = None]
Transports data from global -> register -> shared memory. Does this by warp tile each warp is responsible for moving one warp block of smem.
