42aeb681 - [TensorExpr] Move 'initializer' field from 'Tensor' to 'Buf'. (#50993)

[TensorExpr] Move 'initializer' field from 'Tensor' to 'Buf'. (#50993) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/50993 This is the first step to make 'Tensor` a thin wrapper over 'Buf' and 'Stmt', which will be finished in subsequent PRs. This change also allows to remove 'buf_initializers_' from 'LoopNest', making it "less stateful".
