[PATCH v2 1/3] rust: enable `raw_ref_op` feature

[Antonio Hickey]

Since Rust 1.82.0 the `raw_ref_op` feature is stable.

By enabling this feature we can use `&raw const place` and `&raw mut place`
instead of using `addr_of!(place)` and `addr_of_mut!(place)` macros.

This will allow us to reduce macro complexity, and improve consistency
with existing reference syntax as `&raw const`, `&raw mut` is very similar to
`&`, `&mut` making it fit more naturally with other existing code than
the previously used macros.
