What does this PR do?

As the title says, this PR introduces two modifications:

  1. remove the gradient clipping code related to fairscale FSDP, as fairscale FSDP has been removed. See: remove SharedDDP as it is deprecated #25702
  2. updated the error message when mixing --bf16 and --half_precision_backend apex as the cuda_amp option is no longer available. I'm not sure how to write it more appropriately, so I just use auto instead.

Sounds good, let's rather raise an error here saying that it is no longer supported!

" `--half_precision_backend apex`: GPU bf16 is not supported by apex. Use"
" `--half_precision_backend cuda_amp` instead"
)
raise ValueError(" `--half_precision_backend apex`: GPU bf16 is not supported by apex.")
