Merge #9693 
9693: feat: Add the Hover Range capability which enables showing the type of an expression r=matklad a=alexfertel

Closes https://github.com/rust-analyzer/rust-analyzer/issues/389

This PR extends the `textDocument/hover` method to allow getting the type of an expression. It looks like this:

![type_of_expression](https://user-images.githubusercontent.com/22298999/126914293-0ce49a92-545d-4005-a59e-9294fa2330d6.gif)

Edit: One thing I noticed is that when hovering a selection that includes a macro it doesn't work, so maybe this would need a follow-up issue discussing what problem that may have.

(PS: What a great project! I am learning a lot! 🚀)
