rust: task: add `Send` marker to `Task`

2023-05-31T16:53:10Z

When a type also implements `Sync`, the meaning of `Send` is just "this type may be accessed mutably from threads other than the one it is created on". That's ok for this type.

rust: introduce `current`

2023-04-21T22:20:00Z

This allows Rust code to get a reference to the current task without having to increment the refcount, but still guaranteeing memory safety.

rust: add basic `Task`

2023-04-21T22:20:00Z

It is an abstraction for C's `struct task_struct`. It implements `AlwaysRefCounted`, so the refcount of the wrapped object is managed safely on the Rust side.
