Auto merge of #96770 - flip1995:fix-trait-type-in-bounds, r=cjgillot

Track if a where bound comes from a impl Trait desugar

With https://github.com/rust-lang/rust/pull/93803 `impl Trait` function arguments get desugared to hidden where bounds. However, Clippy needs to know if a bound was originally a `impl Trait` or an actual bound. This adds a field to the `WhereBoundPredicate` struct to keep track of this information during AST->HIR lowering.
