Introduce a new restriction lint to identify casts between pointer-sized integer types (`usize`, `isize`) and fixed-size integer types. Encourage the use of `TryFrom` or `TryInto` over direct `as` casts to make potential platform-specific truncation or zero-extension explicit and handled. Also Provide machine-applicable suggestions to replace risky casts with fallible conversions while excluding constant contexts where such traits are not yet stable. Closes: rust-lang#9231
