Guillaume Gomez fcd75ccc90 Rollup merge of #116540 - daxpedda:once-cell-lock-try-insert, r=Mark-Simulacrum ... Implement `OnceCell/Lock::try_insert()` I took inspiration from [`once_cell`](https://crates.io/crates/once_cell): - [`once_cell::unsync::OnceCell::try_insert()`](874f9373ab/src/lib.rs (L551-L563)) - [`once_cell::sync::OnceCell::try_insert()`](874f9373ab/src/lib.rs (L1080-L1087)) I tried to change as little code as possible in the first commit and applied some obvious optimizations in the second one.
