Streamk functional tests (#2974)
* Add initial fp16_mem_128x128x32_2x2x1_32x32x16_NonPersistent test suite * Account for stride when computing K offsets for A and B tensor This change ensures that the correct stride is used when computing the K offsets into the A and B tensors in the Stream-K Kernel's operator() function. This ensures that the kernel executes correct regardless of whether A and B are row or column major. * Move helper code to test_gemm_streamk_util.hpp * Separate tests into smoke/regression/extended. Add bf16 datatype * Run clang-format * Refactor combinatorial macro expansion and naming * Adjust the initialization values to account for better tolerance on bf16 * Correct BF16 datatypes in comments * Move the extended tests under the REGRESSION_TESTS label * Apply suggestions from code review Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Emily Martins <emily.martins@amd.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
