Add CUDA 12.9 coverage to the DL EP CI job, alongside the existing CUDA 13 path.

This also verifies that import nixl_ep selects the backend matching the CUDA/PyTorch environment before running the DL EP runtime tests. The job still uses the source-built EP artifacts from the PR image.

Run the DL EP source-based test path on both CUDA 12.9 and CUDA 13, and assert that the nixl_ep dispatcher loads the backend matching the active PyTorch CUDA runtime.
