Remove USE_CUTLASS flag (#19271) ### Description Since Cutlass can be built with CUDA 11.4 (The minimum CUDA version for onnxruntime CUDA build), there is no need to have a flag to disable cutlass. Changes: (1) Reverted https://github.com/microsoft/onnxruntime/pull/18761 (2) remove the condition to build cutlass. (3) Fix a few build errors or warnings during testing CUDA 11.4 build. Note that SM 89 and 90 (including fp8) requires CUDA 11.8 or later. Flash attention and cutlass fused multihead attention will not be built for CUDA < 11.6. It is recommended to use CUDA 11.8 or above to build if you want to support latest GPUs. It is better to include it in 1.17.0 (otherwise, the release branch might encounter build failure with CUDA 11.4). Tests: (1) Build with flash attention and efficient attention off: **passed** (2) Build with CUDA 11.4: **passed** Example build command used in Ubuntu 20.04: ``` export CUDA_HOME=/usr/local/cuda-11.4 export CUDNN_HOME=/usr/lib/x86_64-linux-gnu/ export CUDACXX=/usr/local/cuda-11.4/bin/nvcc sh build.sh --config Release --build_shared_lib --parallel --use_cuda --cuda_version 11.4 \ --cuda_home $CUDA_HOME --cudnn_home $CUDNN_HOME --build_wheel --skip_tests \ --cmake_extra_defines CMAKE_CUDA_ARCHITECTURES=80 \ --disable_types float8 ``` ### Motivation and Context <!-- - Why is this change required?
