[fx_acc] [fx2trt] add acc op mapper for argmin and converter for topk (#63823) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/63823 Add mapper for `torch.argmin` which maps it to `acc_ops.flatten` (optional) + `acc_ops.topk` + `acc_ops.getitem` + `acc_ops.squeeze` (optional). This diff doesn't allow mapping if `dim=None && keepdim=True` in `torch.argmin`. Add fx2trt converter for `acc_ops.topk`.
