Add interpolation kwarg to torch.quantile (#49267)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49267
This PR builds upon the PR https://github.com/pytorch/pytorch/pull/48711 by RockingJavaBean. The original PR introduced a BC breaking change by making the interpolation parameter positional. Thus, previous invocations of torch.quantile that did not include the interpolation parameter failed after the PR landed.
To avoid BC breaking changes, we preserve the original signatures and make the interpolation parameter in the new signatures kwarg only. For now, interpolation cannot have a default value to avoid ambiguity with the deprecated signature. However, due to limitations of codegen and C++, we cannot have a required arg after optional ones. Thus, this PR also makes dim and keepdim requires args. Once we can remove the old signatures, dim, keepdim and interpolation parameters in the new signature will get the default values back.
