**Summary:** This was added for torch 2.5 as a placeholder for torch.int4. Now all torch versions we support have these dtypes, so this class is no longer needed and should not be used by anyone. We will remove it next release (0.18.0). **Test Plan:** Manual testing

**Summary:** #4074 and #4100 deprecated a few classes, but this triggered the following warnings when the user imports torchao from the top-level. This commit suppresses these warnings in this case. Before: ``` /data/users/andrewor/ao/torchao/dtypes/utils.py:89: UserWarning: Deprecation: PlainLayout is deprecated and will be removed in a future release of torchao, see #2752 for more details warnings.warn( /data/users/andrewor/ao/torchao/quantization/quant_primitives.py:95: UserWarning: Deprecation: TorchAODType is deprecated, please use the torch.intN dtype instead (e.g. TorchAODType.INT4 -> torch.int4) warnings.warn( /data/users/andrewor/ao/torchao/dtypes/utils.py:89: UserWarning: Deprecation: PlainLayout is deprecated and will be removed in a future release of torchao, see #2752 for more details warnings.warn( ``` After: ``` ``` **Test Plan:** Manual testing.
