Rollup merge of #134277 - notriddle:notriddle/inline-into, r=GuillaumeGomez

rustdoc-search: handle `impl Into<X>` better

This PR fixes two bugs I ran into while searching the compiler docs:

- It omitted an `impl Trait` entry in the type signature field, producing `TyCtxt, , Symbol -> bool`
- It didn't let me search for `TyCtxt, DefId, Symbol -> bool` even though that's a perfectly good description of the function I was looking for (the function actually used `impl Into<DefId>`
