1. [mlir][gpu] Use known_block_size to set maxntid for NVVM target …

   Setting thread block size with `maxntid` on the kernel has great performance benefits. In this way, downstream PTX compiler can do better register allocation.
   
   MLIR's `gpu.launch` and `gpu.launch_func` already has an attribute (`known_block_size`) that keeps the thread block size when it is known. This PR simply uses this attribute to set `maxntid`.
