[turbopack] Make ReadRef using `VcCellMode` semantics, add `VcCellMode::raw_cell` API (#68467) *This is a migrated PR. This was in the turbo repository before the next.js merge.* **Migrated From:** https://github.com/vercel/turbo/pull/8847 ## Description More fixes to `ReadRef` on top of https://github.com/vercel/turbo/pull/8845. There's a bit of a cascade of changes that needed to happen here: - `ReadRef::cell` should actually use `VcCellMode` so that it supports new/shared semantics correctly. - ... however, `VcCellMode` needs to expose an API (`raw_cell`) for working with `SharedReference` so that we can reuse the `SharedReference`/`Arc` inside of `ReadRef` instead of cloning the data inside of it. - ... however, `CurrentCellRef` needs to expose a `compare_and_update` method that works for `SharedReference` (`compare_and_update_with_shared_reference`). - ... however, the naming conventions for the `CurrentCellRef` methods are a bit confusing at this point, so rename them. ## Bigger Picture This my sneaky way of introducing the `raw_cell` API as part of a smaller PR, since that API will be needed for converting a local `Vc` to a resolved `Vc`. That's a similar problem of needing to reuse a `SharedReference` along with `VcCellMode` semantics. ## Testing Instructions ``` cargo nextest r -p turbo-tasks -p turbo-tasks-memory ```
