Rollup merge of #129382 - tgross35:once-cell-const-into-inner, r=Noratrieb
Add `const_cell_into_inner` to `OnceCell` `Cell` and `RefCell` have their `into_inner` methods const unstable. `OnceCell` has the same logic, so add it under the same gate. Tracking issue: https://github.com/rust-lang/rust/issues/78729
