[ROCm] add skipCUDAIfVersionLessThan to unskip test_jiterator for ROCm (#99197)
This unskips 121 tests that the decorator `@skipCUDAIf(_get_torch_cuda_version() < (11, 6))` was unintentionally skipping for ROCm. Other decorators such as `skipCUDAVersionIn` will only activate for the CUDA device, not the CPU or ROCm-as-CUDA.
