2025-09-15rust: sync: extend module documentation of arefBenno Lossin1-0/+15
Commit 07dad44aa9a9 ("rust: kernel: move ARef and AlwaysRefCounted to sync::aref") moved `ARef` and `AlwaysRefCounted` into their own module. In that process only a short, single line description of the module was added. Extend the description by explaining what is meant by "internal reference counting", the two items in the trait & the difference to `Arc`.

2025-09-08rust: sync: Update ARef and AlwaysRefCounted imports from sync::arefShankari Anand1-1/+1
Update the in-file reference of sync/aref.rs to import `ARef` and `AlwaysRefCounted` from `sync::aref` instead of `types`. This aligns with the ongoing effort to move `ARef` and `AlwaysRefCounted` to sync.

Move the definitions of `ARef` and `AlwaysRefCounted` from `types.rs` to a new file `sync/aref.rs`. Define the corresponding `aref` module under `rust/kernel/sync.rs`. These types are better grouped in `sync`. To avoid breaking existing imports, they are re-exported from `types.rs`. Drop unused imports `mem::ManuallyDrop`, `ptr::NonNull` from `types.rs`, they are now only used in `sync/aref.rs`, where they are already imported.
