Auto merge of #17924 - ShoyuVanilla:issue-17921, r=Veykril
fix: Panic when a TAIT exists in a RPIT
Fixes #17921
When there is a TAIT inside of a RPIT like;
```rust
trait Foo {}
type Bar = impl Foo;
fn foo<A>() -> impl Future<Output = Bar> { .. }
```
while inferencing `fn foo`, `insert_inference_vars_for_impl_trait` tries to substitute impl trait bounds of `Bar`, i.e. `Implemented(Foo)` with RPITs `placeholders`, and this causes panic
