8c505bbc - Make ShardedTensor ctor more inline with torch.Tensor ctor (#72164)

Make ShardedTensor ctor more inline with torch.Tensor ctor (#72164) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/72164 torch.Tensor ctor creates an empty tensor and this PR makes ShardedTensor on par with that. In particular we remove TensorInitParams and instead always a create an empty tensor and then fill it in for things like ones, zeros, full etc. This is inline with torch.ones etc. as well since even for those APIs we first create an empty tensor and then fill it out. ghstack-source-id: 148318045 Test Plan: waitforbuildbot Reviewed By: wanchaol Differential Revision: D33934603 fbshipit-source-id: 5655bbd726f29e74600ebe9f33f9dc5952b528f4 (cherry picked from commit 78b301c78c9d5046e2f0a9818dcbc2cc45e7cdd0)
