Revert "[clang][dataflow] Expose simple access to child StorageLocation presence." (#145710) Reverts llvm/llvm-project#145520 Exposed function is no longer needed and side-stepped the intended contract that the present children are the same set returned by `getModeledFields()` and presence shouldn't need to be queried for arbitrary fields.
