Rollup merge of #77514 - scottmcm:less-once-chain-once, r=estebank
Replace some once(x).chain(once(y)) with [x, y] IntoIter

Now that we have by-value array iterators that are [already used](25c8c53dd9/compiler/rustc_hir/src/def.rs (L305-L307))...

For example,
```diff
-        once(self.type_ns).chain(once(self.value_ns)).chain(once(self.macro_ns)).filter_map(|it| it)
+        IntoIter::new([self.type_ns, self.value_ns, self.macro_ns]).filter_map(|it| it)
```
