[PATCH v3 0/4] rust: Add ARef support for work items

[Daniel Almeida]

This series adds ARef<T> support for both regular and delayed work items.

- Patches 1 and 3 actually implement the support in workqueue.rs
- Patches 2 and 4 adds a corresponding implementation in drm::Device that
  dispatches the calls to the underlying T::Data.

This was tested on Tyr, and is actually needed in order to obtain a
&drm::Device when handling work items. This is then needed in order to
allocate GEM objects inside the work handler that processes the tiler OOM
(out of memory) events. The current series sets the stage so that the above
is possible in the future.

Changes in v3:
- Rebase on rust-drm
- Pick up tags
- Fix import style for drm/device.rs changes
- Link to v2: https://lore.kernel.org/r/20260204-aref-workitem-v2-0-bec25b012d2a@xxxxxxxxxxxxx

Changes in v2:
- Rebased on v6.19-rc8
- Cc workqueue maintainers
- Patch 2 kept the old import style, since drm/device.rs is not yet
  converted.
