Gemm multiple d multiple r (#335)
* Imitate XXX_gemm_multiple_d, add XXX_gemm_multiple_d_multiple_r for gemm + reduction * Implement run of kernel * Add example * Fix parameter of typo * Rewrite the reduceMax example * Rewrite the reduceMean + reduceMeanSquare example * Refine naming * Refine folder name * refine naming * Rewrite the gemm + bias + relu + add + layernorm example * Rewrite the gemm + layernorm example * clang-format * Fix bug if sync lds * Fix compile error
