Disable ONNXRuntime CUDA Support, 24.0 branch (2024.03.20.)

Disabled CUDA support for ONNXRuntime on all platforms.

After the recent update to CUDA 12.4 in the main branch, as discussed in ATLINFR-5283, the flag for disabling this CUDA support with GCC 13 was removed from the CI for both main and 24.0. In the past this flag was set in the build system, since on CentOS 7, with GCC 11, we did want to have CUDA support enabled.

But since we're only using a single platform for 24.0, we can disable CUDA support globally like this instead. 🤔 (It will be re-enabled in main after we make all clients compatible with a newer version of ONNXRuntime. Long story...)

Note that this is responsible for warnings in some recent CI builds, like: !69963 (merged). So the sooner it goes in, the sooner the warnings will disappear. 😉
