[CI][CUDA] Move cu118 distributed pull jobs to cu126, move cu124-sm75 to cu126-sm75 (#151594)

Browse Source 
This PR moves distributed cuda CI job from cuda 11.8 to cuda 12.6.
In doing so, a few unit test failures were exposed, some if not all of which would take a while to root-cause and fix, so temporarily skip them after creating the issues.

https://github.com/pytorch/pytorch/issues/153479 test_nan_assert tricky behavior (e.g. skip_but_pass_in_sandcastle, ubuntu 20.04 does not work, ubuntu 22.04 works, Amazon Linux 2023 skip - what is Sandcastle OS?)
https://github.com/pytorch/pytorch/issues/153122 CUDA context related
https://github.com/pytorch/pytorch/issues/153517  NCCL regression, future NCCL may fix it

See: https://github.com/pytorch/pytorch/issues/147383
