Merge #6771

6771: Properly attach inner attributes in Attrs::new r=matklad a=Veykril

Properly attach inner and outer attributes to the things they actually belong to in the HIR. ~~I can add some tests for this if wanted once I know where to put them/how to test for this.~~ Put some tests into `hover.rs`.
 
So the following snippet
```rust
mod foo {
	//! Hello
}
```
now shows `Hello` on hover 🎉

Fixes #2148
