[PATCH v6 12/18] rust: fs: file: refactor to use `&raw const`

[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.
