✨[Converter] Implement aten::embedding

[apbose]

Torch op:
embedding(Tensor weight, Tensor indices, SymInt padding_idx=-1, bool scale_grad_by_freq=False, bool sparse=False) -> Tensor
Aten op : torch.ops.aten.embedding.default

Closing this with #2070. Further needs to be explored for norm implementation
