Auto merge of #117697 - WaffleLapkin:non-null-convenience-ops, r=Amanieu

Non null convenience ops Based on rust-lang/libs-team#251. I went through all of the methods on `*mut` and added every method, which does not require additional safety conditions, to `NonNull`. (exceptions: `guaranteed_eq`, `guaranteed_ne`, `with_metadata_of`, it's unclear if they are useful here...) I'm also not sure what types should the "second pointer parameter" be. `*mut`/`*const` might be more permissible, but given that `NonNull` doesn't coerce to them, it might also be annoying. For now I chose the "use `NonNull` everywhere" path, but I'm not sure it's the correct one... <sub>I'm eepy, so I probably messed up somewhere while copying...</sub> cc `@scottmcm` r? libs-api
