1. New LPGEMM type - S8S8S32/S8 is added. 2. New interface, frame and kernel files are added. 3. Frame and kernel files added/modified for S8S8S32/S8 have 2 operations - Pack B and Mat Mul 4. Pack B kernel routines to pack B matrix for VNNI and compute the sum of every column of B matrix to implement the S8S8S32 operation using the VNNI instructions. 5. Mat Mul Kernel files to compute the GEMM output using the VNNI. Here the A matrix elements are converted from int8 to uint8 (VNNI works with A matrix type uint8 only). 6. Post GEMM computation, additional operations are performed on the accumulated outputs to get the correct results. 7. With this change, two new LPGEMM APIs are introduced in LPGEMM - s8s8s32os32 and s8s8s32os8. 8. All previously added post-ops are supported on S8S8S32/S8 also.
