[Feature] Modifed implementation of BaseDataElement cuda(), cpu(), etc

[YangyangFu]

What is the feature?

The current implementation, such as cuda only supports Tensor, BaseDataElemenet, which doesn't support data strucutures such as BaseInstance3DBoxes. See the below code:

    def cuda(self) -> 'BaseDataElement':
        """Convert all tensors to GPU in data."""
        new_data = self.new()
        for k, v in self.items():
            if isinstance(v, (torch.Tensor, BaseDataElement)):
                v = v.cuda()
                data = {k: v}
                new_data.set_data(data)
        return new_data

why not changing the implementation to work with any data strucutures that has a method of cuda?

Any other context?
