cuda.bindings: Add test_nvrtcGetLoweredName_failure (#499)

* PR #497 squash-merged

* Bring back test_nvrtcGetLoweredName_failure() (it was originally under PR #497).

* Add code for debugging

* test_all_CUresult_codes(): max_code = int(max(cuda.CUresult)) as suggested by at-leofang

* Change pytest options, mostly to disable output capturing (of both stdout and stderr)

* Undo debugging changes in nvrtc.pyx.in

* Revert "Change pytest options, mostly to disable output capturing (of both stdout and stderr)"

This reverts commit b0464e7.

* Skip new test if nvrtc version < 12.1
