10798: ide: show go to for function hover return type r=Veykril a=jhgg

I've found myself wanting this...  adds to the hover quick go-to for a function's return type:

This is particularly useful when you are hovering over a function in a long chain, like:

```rust
foo.bar().b$0az().some_trait_fn();
```

where `baz`'s return type is not immediately obvious, but the chain is not long enough to trigger chain inlay hints... 

i guess I could just select `foo.bar().baz()` too to get the types too...
