IDE: references and call hierarchy for overridden methods

### Describe the Bug

In the IDE, when navigating to references (via `Go to references` or `Show Call Hierarchy`), I would expect it to also show references of the overridden base method. While it's not a direct call, I'd prefer to show it all possible references.

```python
from typing import Protocol, override, cast

class Foo(Protocol):
def foo(self): pass

class FooImpl(Foo):
def foo(self): pass

def a():
cast(Foo, None).foo() # not counted as a reference for FooImpl.foo
def b():
cast(FooImpl, None).foo()

class Bar():
def bar(self): pass

class BarChild(Bar):
@override
def bar(self): pass # not counted as a reference for FooImpl.foo

def c():
cast(Bar, None).bar()
def d():
cast(BarChild, None).bar()
```
