Subject: [PATCH] Fix Conv1d w8a32 operator

Summary:
#### Summary

This diff fixes the Conv1d w8a32 operator by adding a transformation to the `val` attribute of the `other_inputs[0].meta` dictionary. Specifically, the `permute` operation is applied to the `original_val` tensor with the `fake_mode` context, and the resulting `transposed_val` is assigned to `transposed_inputs.meta["val"]`.
