**Description** This PR adds NCU (NVIDIA Nsight Compute) profiling support to the cublaslt-gemm micro benchmark, enabling detailed kernel analysis including DRAM throughput, compute throughput, and launch arguments. **Major Revision** - Add --enable_ncu_profiling and --profiling_metrics for ncu profiling - Modifies command execution to use NCU when profiling is enabled - Updates result parsing to handle both standard and NCU profiled output formats

**Description** Add FP4 precision support for cublaslt_gemm benchmark. **Major Revision** - Add new type `fp4e2m1` and `__nv_fp4_e2m1`. - For FP4 matmul, precision of MatrixC (add) should be FP16, precision of MatricD (output) should be FP4, otherwise, it will not work. - Add macro `CUDA_VERSION` to resolve the compatibility issue of different CUDA versions. --------- Co-authored-by:

**Description** Enable autotuning as an opt-in mode when benchmarking cublasLt via `cublaslt_gemm` The implementation is based on https://github.com/NVIDIA/CUDALibrarySamples/blob/master/cuBLASLt/LtSgemmSimpleAutoTuning/sample_cublasLt_LtSgemmSimpleAutoTuning.cu The behavior of original benchmark command remains unchanged, e.g.: - `cublaslt_gemm -m 2048 -n 12288 -k 1536 -w10000 -i 1000 -t fp8e4m3` The new opt-in options are `-a` (for autotune) and `-I` (for autotune iterations, default is 50, same as the default for `-i`) and `-W` (for autotune warmups, default=20, same as the default for `-w`), e.g.: - `cublaslt_gemm -m 2048 -n 12288 -k 1536 -w 10000 -i 1000 -t fp8e4m3 -a` - `cublaslt_gemm -m 2048 -n 12288 -k 1536 -w 10000 -i 1000 -t fp8e4m3 -a -I 10 -W 10` **Note:** This PR also changes the default `gemm_compute_type` for BF16 and FP16 to `CUBLAS_COMPUTE_32F`. **Further observations:** 1. The support matrix of the `cublaslt_gemm` could be furt...

**Description** Use config `log_raw_data` to control whether log the raw data into file or not. The default value is `no`. We can set it as `yes` for some particular benchmarks to save the raw data into file, such as NCCL/RCCL test.

**Description** This commit does the following to optimize result variance in gpu_copy benchmark: 1) Add warmup phase for gpu_copy benchmark to avoid timing instability caused by first-time CUDA kernel launch overhead; 2) Use CUDA events for timing instead of CPU timestamps; 3) Make data checking an option that is not preferred to be enabled in performance test; 4) Enlarge message size in performance benchmark.
