Revert "Fakify leaf of FunctionalTensor (#107062)"
This reverts commit 3349725766c229b3ead0fb692197d11bd8a85957.
Reverted https://github.com/pytorch/pytorch/pull/107062 on behalf of https://github.com/ydwu4 due to This appears to have broken the test TestDTensorCompile.test_dtensor_fullgraph. Probably a land race ([comment](https://github.com/pytorch/pytorch/pull/107062#issuecomment-1685447747))
