Rollup merge of #72143 - rust-lang:steveklabnik-must-use, r=sfackler
make offset must_use https://djugei.github.io/bad-at-unsafe/ describes an error a user had when trying to use offset: > At first I just assumed that the .add() and .offset() methods on pointers would mutate the pointer. They do not. Instead they return a new pointer, which gets dropped silently if you don't use it. Unlike for example Result, which is must_use annotated. This PR only adds `offset`, because I wanted to float the idea; I'm imagining that there's more than just `add` and `offset` that could use this. I am also very open to re-wording the warning. r? @rust-lang/libs
