Rollup merge of #134285 - oli-obk:push-vwrqsqlwnuxo, r=Urgau

Add some convenience helper methods on `hir::Safety`

Makes a lot of call sites simpler and should make any refactorings needed for https://github.com/rust-lang/rust/pull/134090#issuecomment-2541332415 simpler, as fewer sites have to be touched in case we end up storing some information in the variants of `hir::Safety`
