Kavon Farvardin 545844ce8f ASTPrinter: fix nested signatures with inverses 
A generic signature's `getInnermostGenericParams` will find the generic
parameters in the innermost scope. That's not quite right for printing
inverses, since we don't want to print an inverse for `T` when emitting
the generic signature of `f` below:

```swift
    struct S<T: ~Copyable, E> {
        func f() where E == Never {}
    }
```

Since `f` has its own generic signature, but doesn't define any generic
parameters, it shouldn't have an inverse emitted. The solution here is
to filter inverses by depth of the generic parameter.

We also want to print _all_ of the inverses in other situations, rather
than just the innermost ones. This aids in debugging and other
tools like the API digester.
