What does this PR do?
Fixes #38771.
This PR decouples device_map='auto' and tp_plan='auto'. Before, launching a distributed run when the
device_mapwas set to "auto" triggered TP. We removed that and the user should instead pass tp_plan="auto" or tp_size to tigger TP.Also, we warn/info that this might lead to an unexpected behavior with someone tries to run a distributed run with device_map = "auto".
