[PATCH v5 13/17] rust: sync: arc: refactor to use `&raw [const|mut]`

[Antonio Hickey]

Replacing all occurrences of `addr_of!(place)` with
`&raw const place`.

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