Miguel Ojeda e6ea10d5db Rust hrtimer API for v6.15 ...

Introduce Rust support for the `hrtimer` subsystem:
 
  - Add a way to use the `hrtimer` subsystem from Rust. Rust code can now set up
    intrusive timers without allocating when starting the timer.
 
  - Add support for `Pin<Box<_>>`, `Arc<_>`, `Pin<&_>` and `Pin<&mut _>` as
    pointer types for use with timer callbacks.
 
  - Add support for setting clock source and timer mode.
 
 `kernel` crate:
 
  - Add `Arc::as_ptr` for converting an `Arc` to a raw pointer. This is a
    dependency for the `hrtimer` API.
 
  - Add `Box::into_pin` for converting a `Box<_>` into a `Pin<Box<_>>` to align
    with Rust `alloc`. This is a dependency for the `hrtimer` API.
