Fix crash when non-class is given as supertype

Before this CL this code would crash fasta:
```
class A extends Function() {}
```

Now it produces a compile time error instead:

```
t.dart:1:7: Error: Can't use a function type as supertype.
class A extends Function() {}
      ^
```

(technically it already issued it, but crashed before doing so).

Bug: #36824
