[FRONTEND][PYTORCH] aten:unflatten not supported

[denis-ismailaj]

Got the following error while trying to convert a CLIP model:

NotImplementedError: The following operators are not implemented: [‘aten::unflatten’, ‘aten::scaled_dot_product_attention’]

There is already an open issue for aten::scaled_dot_product_attention (#15361), so I'm creating this one for aten::unflatten.

I'll work on it.
