## Summary
Working on py-fuzzer recently (AKA, a Python project!) reminded me how
cool our "inlay hint goto-definition feature" is. So this PR adds a
bunch more of that!
I also made a couple of other minor changes to type display. For
example, in the playground, this snippet:
```py
def f(): ...
reveal_type(f.__get__)
```
currently leads to this diagnostic:
```
Revealed type: `<method-wrapper `__get__` of `f`>` (revealed-type) [Ln 2, Col 13]
```
But the fact that we have backticks both around the type display and
inside the type display isn't _great_ there. This PR changes it to
```
Revealed type: `<method-wrapper '__get__' of function 'f'>` (revealed-type) [Ln 2, Col 13]
```
which avoids the nested-backticks issue in diagnostics, and is more
similar to our display for various other `Type` variants such as
class-literal types (`<class 'Foo'>`, etc., not ``<class `Foo`>``).
