docs: add build instructions for NVIDIA Jetson (aarch64 + CUDA) - #2019
Merged

Conversation
The prebuilt aarch64 wheels on PyPI are CPU-only. Add instructions for building from source with CUDA on Jetson devices (JetPack 6.x), including the required cmake flags and a note in hardware_support.md. Tested on Jetson Orin Nano with JetPack 6.x, CUDA 12.x, Python 3.10. Relates to OpenNMT#1908.

Could we use python -m pip install --force-reinstall dist/ctranslate2*.whl here? Otherwise pip may keep the CPU-only wheel if the same version is already installed.
| git clone --recursive https://github.com/OpenNMT/CTranslate2.git | ||
| cd CTranslate2 | ||
| mkdir build && cd build | ||
| cmake .. -DWITH_CUDA=ON -DWITH_CUDNN=ON -DWITH_MKL=OFF -DOPENMP_RUNTIME=COMP |

Could we also add -DWITH_RUY=ON? With MKL disabled, this build has no CPU matrix multiplication backend, so CPU inference won’t work.
