Enable RISC-V 64-bit Cross-Compiling Support for ONNX Runtime on Linux (#19238) ### Description This pull request introduces the necessary changes to enable RISC-V 64-bit cross-compiling support for the ONNX Runtime on Linux. The RISC-V architecture has gained popularity as an open standard instruction set architecture, and this contribution aims to extend ONNX Runtime's compatibility to include RISC-V, thereby broadening the reach of ONNX models to a wider range of devices. ### Motivation and Context RISC-V is a free and open-source instruction set architecture (ISA) based on established RISC principles. It is provided under open licenses without fees. Due to its extensibility and freedom in both software and hardware, RISC-V is poised for widespread adoption in the future, especially in applications related to AI, parallel computing, and data centers. ### Example Build Command ``` ./build.sh --parallel --config Debug --rv64 --riscv_toolchain_root=/path/to/toolchain/root --skip_tests ``` ### Documentation Updates Relevant sections of the documentation will be updated to reflect the newly supported RISC-V 64-bit cross-compilation feature. https://github.com/microsoft/onnxruntime/pull/19239 --------- Signed-off-by: Phoebe Chen <phoebe.chen@sifive.com>
