[BYOC] TensorRT testing issues

[mbs-octoml]

Here is the state of tests/python/contrib/test_tensorrt.py in CI:

• test_maskrcnn_resnet50 is skipped since it is sensitive to LLVM/PyTorch JIT mismatches.
• test_conv3d is skipped since it fails the assert_allclose.
• the remaining tests are only run with run_module=False since the ci-gpu image has
  set(USE_TENSORRT_CODEGEN ON) but set(USE_TENSORRT_RUNTIME OFF).
